Question

Factor each trinomial

x^2-2x-15

Answer 1

Factors will be 2 binomials. in the form (x + ) (x - ) since the constant term is a -15
Try to factor -15 so that the sum of the factors will = -2
it will be -5 and 3
The factors will then be (x - 5) (x - 3)
You can check your answer by multiplying the factors using FOIL and it will give you back the trinomial.
Oops it should be (x+3)(x-5)
