Question

Which of the following shows the complete factorization x3 + 3x2? A. x2(x – 3) B. x(x2 + 3x) C. x2(x2 + 3) D. x2(x + 3)

Answer 1

x^3 + 3x^2
x (x^2 + 3x)
x^2 (x + 3)

Answer is D

Answer 2

The complete factorization of the x ³ + 3x² is x²(x + 3).

Option (D) is correct .

Explanation:

As given the expression given in the question as follow.

= x ³ + 3x²

Taking x² as common part.

thus the expression becomes

= x²( x + 3)

Therefore the complete factorization of the x ³ + 3x² is x²(x + 3).

Option (D) is correct .
