Question

What is the factorization of the polynomial below?
x^2+11x+10
A. (x+5)(x+6)
B. (x+8)(x+3)
C. (x+10)(x+1)
D. (x+2)(x+5)

Answer 1

The first term is x^2. So the set up will look like (x )(x ).

Answer 2

Now, look for factors of 10 that add to 11, and when multiplied get you 1.

Answer 3

10* not 1

Answer 4

Then its C right?

Answer 5

Yep!

Answer 6

Thanks.

Answer 7

No problem. Also, always check your work with FOIL method and see if the factored version comes to the original polynomial.
