What is the LCM for (x + 3)2(x – 2) and (x + 3)(x2 – 16)? A. (x + 3) B. (x + 3)(x – 2)(x – 16) C. (x + 3)3(x – 2)(x2 + 16) D. (x + 3)2(x – 2)(x2 – 16)

Respuesta :

Answer:

2(x-2)(x+3)(x-8)

Step-by-step explanation:

The LCM of [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex] is x + 3

Option A is correct

The task is to find the LCM of the expressions:

[tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex]

Note that:

[tex](x^2-16)=(x-4)(x+4)[/tex]

Therefore, the expression [tex](x+3)(x^2-16)[/tex] will become:

[tex](x+3)(x-4)(x+4)[/tex]

By considering the expressions [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex], it is observed that x + 3 is common to both expressions.

Therefore, the LCM of [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex] is x + 3
