Question

How do you factor the trinomial `x^2-11x+18`?

Answer 1

Find two numbers that posses the product of the c term (last term, without a variable) and the sum of the b term (the middle term, with an x coefficient, degree one)

Explanation:

`x^2` - 11x + 18 ---> -9 - 2 = -11 and -9 • -2 = 18
= (x - 9)(x - 2)
