So, let's solve 3x^2-3x-2x+2=-17x+8
1) Simplify both sides.
3x^2-5x+2=-17x+8
2) Write equation in standard form. Polynomial on the left side, and 0 on the right.
3x^2+12x-6=0
3) Divide by the current lead coeffecient, which is 3.
1x^2+4x-2=0
4) Move constant to the right side of the equation.
1x^2+4x=2
5) Square the number
(x+2)^2=6
6) Solve the equation.
Hope I helped.
