x3 + 2x2 - 19x - 20 = x3 + x2 + x2 + x - 20x - 20 = x2(x + 1) - x(x + 1) - 20(x + 1)
= (x + 1)(x2 + x - 20) = (x + 1)(x - 4)(x + 5)

a2+9a+20 = (a+4)(a+5) when factored
What is the ratio of teachers to students if there are 500 students and 25 teachers?
We figure this out by dividing 500 by 25. The answer is 20, so the ratio is 1 teacher for 20 students.
-4x2 plus 6x plus 40 equals 0?
-4x2 + 6x + 40 = 0 ∴ -2x2 + 3x + 20 = 0 ∴ -2x2 - 8x + 5x + 20 = 0 ∴ -2x(x + 4) + 5(x + 4) = 0 ∴ (5 - 2x)(x + 4) = 0 ∴ x ∈ {5/2, -4}
