What polynomial factors as (x-4) (x+13) ?
FOIL (First, Outer, Inner, Last)
x*x = x^2
x * 13 = 13x
-4 * x = -4x
-4 * 13 = -52
---
(x^2 + 13x - 4x -52)
---
x^2 + 9x - 52
===
What polynomial factors as (q-7) (q+10) ?
q^2 +10q - 7q -70
---
q^2 + 3q - 70
===
t^2 + 18 t - 40
---
Factor
(t-2)(x+20)
===
d^2 + 2 d - 99
---
does not factor
