Answer:

which pair of numbers has a product of ac and a sum of b

ac = (-5)(-3)

sum = -8

x^2 - 5x - 3x + 15

x(x-5)-3(x-5)

(x-3) (x-5)

x=3 x=5

what is the factored form of the trinomial = (x - 3) (x - 5)

2. Factor the following:

x^2 - 8 x + 15

The factors of 15 that sum to -8 are -3 and -5. So, x^2 - 8 x + 15 = (x - 3) (x - 5):

Answer:  (x - 3) (x - 5)
