Question

Factors of 3x³ – 2x² – 8x are ______.

विकल्प

• x(3x² – 2x – 8)

• x(x – 2)(2x + 1)

• 2x(x – 4)(2x + 1)

• x(x – 4)(2x + 1)

Answer 1

Factors of 3x³ – 2x² – 8x are x(x – 2)(2x + 1).

Explanation:

3x³ – 2x² – 8x = x(3x² – 2x – 8)

= x(3x² – 6x + 4x – 8)

= x[3x(x – 2) + 4(x – 2)]

= x(3x + 4)(x – 2)
