Question

2 Factor into two binomials: x2 + 9x + 18 Question 2 options: A) (x + 9) B) (x + 2) C) (x + 4) D) (x + 18) E) (x + 6) F) (x + 3)

Answer 1

Since the leading coefficient of the quadratic is 1, we only need to find a factor pair of 18 that can be used to get a positive 9 .. this would be the factor pair of 3 and 6.

Your factored form would be (x+3)(x+6)
