Question

Choose two trinomials from the list below to factor. Using complete sentences, explain how to factor each one. Be sure that the final factorization (or "answer") is a part of your explanation.


2x2 + 13x + 15
2x2 + 27x + 13
5x2 − 2x − 7
10x2 − 7x − 3
8x2 − 11x + 3

Answer 1

2x^2 + 13x + 15 -> (x+5) (2 x+3)
2x^2 + 10x + 3x + 15
2x(x + 5) + 3(x + 5)
(2x + 3)(x + 5)


2x^2 + 27x + 13 -> (x+13) (2 x+1)
2x^2 + x + 26x + 13
x(2x + 1) + 13(2x+1)
(x+13)(2x+1)
