Factoring trinomials
Find the GCF: 3x2, 12x
3x
Find an integer value of b that makes x2 + bx - 15 factorable, and then factor the trinomial.
b = -14 (x-15)(x+1)
b = 14 (x+15)(x-1)
b = 2 (x+5)(x-3)
b = -2 (x-5)(x+3)
Determine whether the value of c makes 3x2 + 7x + c factorable. If it is, factor it.
c = -2
Cannot be factored
Determine whether the value of c makes 3x2 + 7x + c factorable. If it is, factor it.
c = 2
(3x + 1)(x + 2)
