Our answer is x² + 10x + 25.

We are asked to expand the following expression:
(x + 5)(x + 5)
In order to multiply two binomials, use FOIL:
- F = first
- O = Outside
- I = Inside
- L = Last
multiply the first terms -
x * x = x^2
multiply the outside terms -
x * 5 = 5x
multiply the inside terms -
5 * x = 5x
multiply the last terms -
5 * 5 = 25
