3. Factor the following trinomial.
x2 - 15x+ 56
Step 1: The trinomial factors as x2 + bx + C = (x + p)(x+ 9), where pt 9-van
= c. Fill in the
*DX+C= (x+ P(x + ), where p + q = band p.
g table with all of the possible values of p and q, using the fact that their product is the
constant term, c = 56. (4 points)
