Answer 3

So I don't need to put on my calculator (x+5)*(x+5)?

Answer 4

Doing the three it gave 3375

Answer 5

no this is algebra and you use whats known as the Distributive Law

first multiply the second parenthesis by x then by +5:

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

are you familiar with algebra?

Answer 6

Yea, Damn I need to do distribute property?

Answer 7

yes

then second step is

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

Answer 8

and simplify as I did before
