To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x
Start off by distributing the x to x+2.
X^2+2x
X+x+3
ADD EVERYTHING TOGETHER
X^2+4x+3
X^2+2x
X+x+3
ADD EVERYTHING TOGETHER
X^2+4x+3
