Expand and simplify:

(x+2) (x+2)

Use foil which is a lazy way to remember theh distributive property

goes like this

multiply

First terms

Outer terms

Inner terms

Last terms

and add them all toegethe

so

(x+2) (x+2)

First: x times x or x²

Outer: x times 2 or 2x

Inner: 2 times x or 2x

Last: 2 times 2 or 4

add them toegether

x²+2x+2x+4=

x²+4x+4
