Answer 8

Set equal to 0:

x^2 - 3x + 4 = 0

Now find a, b such that a + b = -3 and ab = 4

Let a = -4, b = 1:
(x - 4)(x + 1) = 0

So either (x-4) = 0 or (x+1) = 0... what situations can this happen in? Either x = 4 or x = -1. Nothing else will cause one of those terms to equal zero. That's why it has 2 roots.
