Factoring Trinomials

Watch this video for examples. Factor the trinomial: x2 + 7x +10 (x + 5)(x - 2) (x - 5)(x+2) (x + 5)(x+2) (x- 5)(x - 2) Factor the trinomial: x2 + x - 12 (x - 4)(x + 3) (x + 4)(x- 3) (x + 6)(x - 2) (x - 4)(x-3) Factor the trinomial: x2 + 8x + 7 (x - 7)(x + 1) (x + 7)(x - 1) (x - 7)(x - 1) (x + 7)(x + 1) Factor the trinomial: x2 - 36 (x + 6)(x + 6) (x- 6)(x + 6) (x - 6)(x - 6) (x - 4)(x + 9) Factor the trinomial: x2 - 6x + 9 (x - 3)(x + 3) (x - 3)(x- 3) (x+ 3)(x + 3) (x + 1)(x - 9) Factor the trinomial: x2 - 2x - 24 (x + 6)(x- 4) (x - 6)(x- 4) (x - 6)(x+ 4) (x + 6)(x+ 4) Which expression is a factor of the trinomial, x2 - 17x + 72? (x + 8) (x + 9) (x - 12) (x - 9)
