Question

3x^2+4x-2=0

Answer 1

quadratic formula?

Answer 2

x=-2/3 x=1

Answer 3

yes, and i need to show my work.

Answer 4

I don't think it's x= -2/3,
you need to use the quadratic formula.

Answer 5

x^2-4x+6 = 0
(x+2/3) (x-3/3)
(3x+2)(x-1)

Answer 6

but (3x+2)(x-1) = 3x^2 -3x +2x -2 = 3x^2 -x -2
incorrect D:

Answer 7

again, quadratic formula just use it.

Answer 8

im not sure how to do that.

Answer 9

\[\frac{ -b \pm \sqrt{b^{2} + 4ac} }{ 2a}\]
and we also have
\[ax^{2} + bx +c\]
in this case
a= 3
b= 4
c= -2

All you need to do is plug a, b , and c in the equation
then simplify

Answer 10

plug it in the first equation

Answer 11

Alright, thank you
