x^2-3x+2=0
x^2-x-2x+2=0
x(x-1)-2(x-1)=0
(x-1)(x-2)=0
x-1=0 hence x=1
x-2=0 hence x=2
therefore:
x=1,2


Hope this helps,

Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=1 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 2, 1. Here's your graph:
