Question

f(x)=-6x^2+5x+3

A.-124,0,40
B.-6,5
C-0.83,-0.50
D.-2.00,1.67

Answer 1

You are factoring, I presume? Do you know the quadratic formula?

Answer 2

yes
\[\frac{-b+-\sqrt{b^2-4(a)(c)} ? }{ 2(a) }\]

Answer 3

So your a = -6, your b = 5, and your c = 3. Right? So fill them in.

Answer 4

I did this three times and got the same factors all three times and none of them are your answers. I want to see what you get.

Answer 5

Awe heck im suck at math thats why Im here to try and get help

Answer 6

ok, but did you maybe copy something wrong? Either the equation or the answers? The first choice in your answers is a bit skewed. Check your typing and let me know. Ok? We can help you.

Answer 7

If you can remember that quadratic formula, that's over half the battle here. The other half is getting the answers and equations correct. So check that for us.

Answer 8

This work?

Answer 9

Way better! Are you working on this one now?

Answer 10

trying but I'm stuck math is extremely difficult for me I have a TBI

Answer 11

I don't know what that is, but I can help you anyways, ok? Let's use that equation and fill in the quadratic formula with a = -5, b = 4, c = 9, ok?

Answer 12

Traumatic Brain Injury
ok

Answer 13

\[\frac{ -4\pm \sqrt{(4)^{2}-4(-5)(9)} }{ 2(-5) }\]

Answer 14

Im an Injure Marine

Answer 15

injured*

Answer 16

You'll get it; like I said you remembered the quadratic formula. That's a good thing! Sorry to hear you got hurt. : (

Answer 17

8+180?

Answer 18

\[\frac{ -4\pm \sqrt{16+180} }{-10 }\]

Answer 19

188/-10?

Answer 20

Be careful...4 squared is 16 not 8.

Answer 21

\[\frac{ -4\pm \sqrt{196} }{ -10 }\]

Answer 22

now divide that by 10?

Answer 23

the square root of 196 has a perfect square in it...14. So that means we have this now: (it's a -10, don't forget)\[\frac{ -4\pm14 }{ -10 }\]

Answer 24

There are two solutions in there now:\[\frac{ -4+14 }{ -10 }\]and\[\frac{ -4-14 }{-10 }\]

Answer 25

That plus/minus sign is what gives you the two different--very different--solutions we get for the zeros.

Answer 26

\[\frac{ -4+14 }{ -10 }=\frac{ 10 }{-10 }=-1\]

Answer 27

\[\frac{ -4-14 }{ -10 }=\frac{ -18 }{ -10 }=\frac{ 9 }{ 5 }\]

Answer 28

so how does the choices I gave you come into play?

Answer 29

well, let's divide 9 by 5 and see what we get. 9/5 = 1.8. So we have x = -1.00 and
x = 1.8

Answer 30

See it there?

Answer 31

right I got 1.8

Answer 32

Cool! See! Not too bad...just keep your positives and negatives in order and you'll do a fine job!

Answer 33

Im saying but that is no where on the choice you seen the file right?

Answer 34

nvm sorry

Answer 35

Right...it's the last choice on the second screenshot you sent. {-1.00, 1.80}

Answer 36

you leave me :-(
