Question

does anyone have the answer i have the multipule choice to it

Answer 1

what is the question?

Answer 2

solve the quardatic equation for x

Answer 3

do you know what the quadratic formula is?

Answer 4

i have the multipul choice answers

Answer 5

i posted it

Answer 6

Please post a question with the full description of the problem. If you don't we can't help you.

Answer 7

(7x-2)(6x+4)

Answer 8

10x^2+6x-28
=2(5x^2+3x-14)
=2(5x-7)(x+2)
5x-7=0 --->x=7/5
x+2=0 --->x=-2

Answer 9

thats wrong. You can't use the quadratic

Answer 10

That is not wrong. It is factored and those factors set equal to 0. Solve from there. Not wrong...

Answer 11

(7x-2)(6x+4)
42x^2 + 28x - 12x -8
42x^2 + 16x - 8

42x^2 + 16x - 8 = 0

Roots = [ -b +- sqrt{ b^2 - 4ac ] / 2a

Answer 12

Sorry, I thought you meant mine was wrong..Lol..I was like..NO

Answer 13

here are the multip. ans. a x= -7/2 or 3/2 b x=7/2 or -3/2 c =2/7 or -2/3 d x=-2/7or 2/3

Answer 14

answer is:

-2/3 and 2/7

Answer 15

really? first you must understand why we set them to 0
you can't just ask (7x-2)(6x+4) what are the values of x without understanding why we have to set it to 0. Heck we can set it up as anything.

Answer 16

it just says solve the quadratic equation for x (7x-2)(6x+4)

Answer 17

above are the possible answers

Answer 18

In the answers why are there two values?

Answer 19

thats why im here lol

Answer 20

It means find the roots of that quadratic equation..which is where the y values are equal to 0, therefore we set the equation equal to 0. Hence the two answers..

Answer 21

(7x-2)=0 --->x=2/7
(6x+4)=0 --->-2/3

Answer 22

yeah I just think she wants the answers

Answer 23

answer is C
