Question

Factorize 4x^3 -8x^2- 12x

Answer 1

Answer:4x^3 -8x^2- 12x

Taking common4 x

4X(x²-2x-3)

Doing middle term factorization

4x(x²-3x+x-3)

4x(x(x-3)+1(x-3))

4x(x-3)(x+1) is your answer

Explanation:

Answer 2

Explanation:

4x³ - 8x² - 12x = 4x ( x² - 2x - 3)

= 4x (x² + x - 3x - 3*1)

= 4x [ x(x + 1) - 3(x +1)]

= 4x [ (x +1) (x - 3)]

= 4x (x + 1)(x-3)
