Question

help

Answer 1

do you know how to expand the left hand side?

Answer 2

For this one no.. I'm a little confused

Answer 3

(x-3) (x+2)

basically multiply it out X multiply X followed by -3 multiply X then X multiply 2 lastly -3multiply 2

Answer 4

x^2+x-6?

Answer 5

or would it be x^2+2x-6

Answer 6

should be x^2 - x - 6

Answer 7

why -x

Answer 8

x multiply -3 = -3x
x multiply 2 = 2x
so -3x+2x= -x

Answer 9

oooo

Answer 10

you do know how to use foil in math right?

Answer 11

I used to but it has been years

Answer 12

no problem.

Answer 13

we have establish the left hand side is\[x ^{2}-x-6\]

Answer 14

we then proceed to move everything from the right to the left

Answer 15

first we move the 2. Since the right hand side is divide by 2 when we move it we multiply the left hand side by 2

Answer 16

\[2(x ^{2}-x-6)\]

Answer 17

\[2x ^{2}-2x-12\]

Answer 18

So that 2 came from the other side?

Answer 19

next we move the 2x from the right side to the left side which will look like
\[2x ^{2}-2x-2x-12=35\]

Answer 20

yes the 2 came from the right hand side

Answer 21

Ok so far this is making sense.. would I now subtract the 35 to get it on the other side so the equation = 0

Answer 22

you got it

Answer 23

you should get \[2x ^{2}-4x-47=0\] as your equation

Answer 24

\[-4+-\sqrt{(4)^{2}}-4(2)(-47)/2(2)\]

Answer 25

right? I just do the quadtratic formula now?

Answer 26

yes

Answer 27

Thank you so much :)

Answer 28

no problem but you should check see if my math is right or not haha i might add or dropped something by accident

Answer 29

haha ok

Answer 30

plus you know your square root is rooting the whole b^2 - 4AC right not just the b^2

Answer 31

yeah lol I just have never used the equation thing before so I didn't know how to type it right.

Answer 32

\[\sqrt{b ^{2}-4ac}\]

Answer 33

okay just making sure
