Someone and explain how you get the answer step by step

I'll do number 11 for you so that you can understand, and do the rest on your own.

Step-by-step explanation:

Number 11 asks to factor x^2+3x+2.

So you have to find a number that multiples to equal 2, but adds to equal 3.

You know that when you multiply 2 and 1 you get 2, and when you add 2 and 1, you get 3.

So, it would be factored into (x+2)(x+1)
