Question

Find the product of (x + 5)2. x2 − 10x + 25 x2 − 25 x2 + 25 x2 + 10x + 25

Answer 1

D. x2 + 10x + 25

Explanation:

Answer 2

Answer: Last option.

Explanation:

By definition, the square of a binomial is:

`(a+b)^2=a^2+2ab+b^2\\\\(a-b)^2=a^2-2ab+b^2`

Keeping the above on mind, you have the following expression given in the problem:

`(x+5)^2`

Therefore, if:

`a=x\\b=5`

You obtain the following trinomial:

`(x+5)^2=x^2+2(x)(5)+5^2=x^2+10x+25`

Therefore, the answer is the last option.
