Could you check my answer?
y = x^2 + 3x + 2

List all the factors of 2:
1 * 2 = 2
-1 * -2 = 2

Find the product of 2 and sum of 3.
1 * 2 = 2 and 1 + 2 = 3

Place the numbers into a binomial:
(x + 2)(x + 1)

Is that right? It just seems too simple to be the right answer.

you are correct, x^2 + 3x + 2 factors to (x+2)(x+1)

anonymous · Answer

to check yourself, all you gotta do is multiply the factors back together.

jim_thompson5910 · Answer

Check:

(x+2)(x+1) = x(x+1) + 2(x+1)

(x+2)(x+1) = x*x+x*1 + 2*x+2*1

(x+2)(x+1) = x^2+x + 2x + 2

(x+2)(x+1) = x^2 + 3x + 2
