Question

Select one of the factors of 3x² + 4x - 4.

O (x + 4)
O (3x + 2)
O (3x - 2)
O(x - 2)

Answer 1

(3x-2)

Explanation:

3x² + 4x - 4

look for two factors whose product is (3)(-4)=-12 and sum is +4

The factors will be +6 and -2

substitute these factors inplace of 4x to get:

3x² - 2x + 6x - 4

then factorize:

x(3x-2)+2(3x-2)

finally we get factors: (3x-2)(x+2)
