Question

Expand: (m + 4) 0 m2 + 8m + 16 0 m2 + 4m + 16 O mp + m +- 8

Answer 1

we have the next squared binomial

`(m+4)^2`

we have the next formula in order to expand a squared binomial

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

So we can expand

`(m+4)^2=m^2+2(4)(m)+4^2=m^2+8m+16`

so the correct answer is the first one
