x = 2, 1
Step-by-step explanation:
so first we want to factor, this one is a simple one to factor since it doesn't have a number other than 1 in the first term
what multiplies to 2 and adds to - 3
-2 and - 1
so we set out our binomials as
(x - 2) (x - 1)
then we set each of these to zero (of course it's easier just to swith the signs, but it doesn't work the same if there is a number other the one in front of the x ... EX: (2x-2) (3x + 4))
x - 2 = 0
+2 + 2
x = 2
and
x - 1 = 0
+1 + 1
x = 1
so the solution, or the zeroes are x = 2, 1
