Question

I don't really need help here, I'm just using this as a workspace for my test on quadratic equations. :P

Answer 1

\[\Large x= \frac {-b \pm sqrt{b^{2}-4ac}{2a}\]

Answer 2

HIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

Answer 3

stahp it

Answer 4

@saifoo.khan I can't see my equation! D:

Answer 5

Wear some glasses maybe?

Answer 6

Don't forget to close a curly bracket.
\[\Large x= \frac {-b \pm \sqrt{b^{2}-4ac}}{2a}\]

Answer 7

No, like, it's grey, and not loading. I have the thing that says Processing math: 100%

Answer 8

and it WON'T GO AWAY. >:(

Answer 9

Maybe I'm using a bad proxy.

Answer 10

Maybe.

Answer 11

\[\Large x= \frac {-b \pm \sqrt{b^{2}-4ac}}{2a}\]

Answer 12

I can see it! It was just a bad proxy :P

Answer 13

\[\Large x=\frac{ -10\pm \sqrt{10^{2-4(-20)}} }{ 2 }\]

Answer 14

\[\Large x=\frac{ -10\pm \sqrt{2} -4(-20) }{ 2 }\]*

Answer 15

GAH

Answer 16

\[\Large x=\frac{ -10\pm \sqrt{2-80} }{ 2 }\]

Answer 17

\[\Large x=\frac{ -10\pm \sqrt{-78} }{ 2 }\]

Answer 18

\[\Large x=-5 \pm \sqrt{-39}\] @hba did I do this step right?

Answer 19

Where are we ?

Answer 20

I think I did this equation completely wrong. That's not one of the answer choices ._.

Answer 21

You always do it wrong,give me a question let me show how it goes.

Answer 22

\[\Huge x ^{2} = 10x -20\]

Answer 24

Helpful. :P

Answer 25

So,

x^2-10x+20=0


Here

a=1

b=-10

c=20

in quad formula.

@poopsiedoodle Do it for me.

Answer 26

\[\Large x=\frac{ -10\pm \sqrt{10 - (4(20))} }{ 2 }\]

Answer 27

since, a = 1, I just took out a.

Answer 28

@poopsiedoodle

Write it again correctly

You have done a mistake

Answer 29

oops. 10^2*
\[x=\frac{ -10 \pm \sqrt{10^{2}-4(20)} }{ 2 }\]

Answer 30

One more mistake

Answer 31

I'm not seeing it o-o

Answer 32

The only thing I can think of is leaving out the 1, which isn't necessary to include since it doesn't effect the outcome of the problem.

Answer 33

Try seeing it

Mistake of sign

Answer 34

OH

Answer 35

\[x=\frac{ 10\sqrt{-10 - 4(20)} }{ 2 }\]

Answer 36

Where is the +- sign ?

Answer 37

Where did the square go

Answer 38

The underroot is on the whole exp.

Answer 39

omg I keep forgetting things

Answer 40

It is

4(a)(b) not only 4(c)

Answer 41

4(a)(c) *

Answer 42

\[\huge x=\frac{ 10\pm \sqrt{-10^{2} - 4(1)(20)} }{ 2(1) }\]

Answer 43

Continue.

Answer 44

@poopsiedoodle

Answer 45

\[\huge x=\frac{ 10\pm \sqrt{100 - 4(20)} }{ 2 }\]

Answer 46

\[\huge x=\frac{ 10\pm \sqrt{100 - 80} }{ 2 }\]

Answer 47

\[\huge x=\frac{ 10\pm \sqrt{20} }{ 2 }\]

Answer 48

Yes :)

Answer 49

\[\huge x=\frac{ 10\pm 4\sqrt{5} }{ 2 }\]

Answer 50

^ this is wrong.

Answer 51

\[\huge x={ 5\pm \sqrt{4*5} }\] *

Answer 52

When you take sqrt{20}=sqrt{5*4]=2sqrt{5}

\[\huge x=\frac{ 10\pm 2\sqrt{5} }{ 2 }\]

Now continue....

Answer 53

\[\Huge x=10\pm \sqrt{5}\]

Answer 54

I'd nominate you for helper of the month, if that was a thing.

Answer 55

now time for another one! :D

Answer 56

\[\Huge 0 = -3x ^{2} 33x+24\]

Answer 57

No YOU ARE WRONG!!


We are taking 2 common through out.

Answer 58

wat

Answer 59

\[\huge x=\frac{ 2(5\pm \sqrt{5}) }{ 2 }\]

Answer 60

so yeah, \[\Huge x= 5 \pm \sqrt{5}\]

Answer 61

hmm

Answer 62

Now then, on to \[\Huge 0 = -3x^{2} + 33x +24

Answer 63

oops

Answer 64

\[\Huge 0 = -3x^{2} + 33x +24\]

Answer 65

Here

a=-3

b=33

c=24


in quad formula

Answer 66

\[\huge x = \frac{ 3\pm \sqrt{-3^{2} - 4(-3)(24)} }{ 2(-3) }\]

Answer 67

b=33 not 3

Answer 68

erpsh.

Answer 69

\[\Huge x = \frac{ 33\pm \sqrt{-33^{2} - 4(-3)(24)} }{ 2(-3) }\]

Answer 70

Sign error

Answer 71

\[\Huge x = \frac{ -33\pm \sqrt{33^{2} - 4(-3)(24)} }{ 2(-3) }\]

Answer 72

Continue.

Answer 73

\[\Huge x = \frac{ 33\pm \sqrt{-33^{2} - 288} }{ 2(-3) }\]

Answer 74

The sign :/

Answer 75

+288?

Answer 76

I was kinda confused on that part.

Answer 77

What about -33 also

Answer 78

Yes +288 because (-) (-)=+

Answer 79

oops.

Answer 80

\[\Huge x = \frac{ -33\pm \sqrt{33^{2} + 288} }{ 2(-3) }\]

Answer 81

YEs continue

Answer 82

\[\Huge x = \frac{ -33\pm \sqrt{33^{2} + 288} }{ -6 }\]

Answer 83

\[\Huge x = \frac{ -33\pm \sqrt{1089 + 288} }{ -6 }\]

Answer 84

das a big ol' numba doe.

Answer 85

Continue.

Answer 86

\[\Huge x = \frac{ -33\pm \sqrt{1377} }{ -6 }\]

Answer 87

I think the 1377 breaks down into 17 and 81 here.

Answer 88

\[\Huge x = \frac{ -33\pm \sqrt{17*81} }{ -6 }\]

Answer 89

\[\Huge x = \frac{ -33\pm 9\sqrt{17} }{ -6 }\]

Answer 90

well, I gotta go home now. I may or may not be back soon.

Answer 91

Now take 3 common

Answer 92

\[\Huge x = \frac{ -11\pm 3\sqrt{17} }{ -2 }\]

Answer 93

Yeah right :)

You can also take -1 common throughout.

But,this answer is also correct
