Question

Multiply 2x(x2 + 5).

A) 2x3 + 10x2
B) 2x3 + 10x
C) 2x2 + 10x
D) 2x3 + 5x

Answer 1

The correct answer is B). 2x3 + 10x, this is because

2x(x2) gets you 2x3, because you just add an x instead of multiplying the x.

And 2x times 5 is 10x, because 2 x 5 is 10, and you just put the x on the ten to get 2x3 + 10x
