Question

What is equivalent to (x+7)^2 ?

1. x^2+49

2. (x-7)(x+7)

3. (x+7)(x+7)

4. (7x)(7x)

Answer 1

⇒In this case what is in the brackets is being treated as being the term . so this means that if we are to expand then we expand the whole term in full detail.

⇒In this case we have x+7 as the term of the expression which means when we expand we are going to expand the whole term x+7

`=(x+7)^(2) \\=(x+7)(x+7)`

The third option is the answer.

GOODLUCK!!
