Question

(x – 4 )(3x + 2) = 0 Solve for x, show work.

Answer 1

since if we have a*b=0, we have a=0 or b=0

Answer 2

first: FOIL it (first outer inner last)
x times 3x
x times 2
-4 times 3x
-4 times 2

Answer 3

set both factors equal to zero

Answer 4

x-4=0 or 3x+2=0

Answer 5

x=4 or 3x=-2

Answer 6

x=4 or x=-2/3

Answer 7

myininaya is correct.. do not foil this....

Answer 8

now you should have 3x^2 + 2x - 12x - 8 = 0

from here combine like terms

now you should have 3x^2 - 10x - 8 = 0
