1. 2(x+3)squared-6x+5=0
Answer= 2xsquared+6x+23=0
2. 3xsquared-6x+5=-2(x+1)-10
Answer= 3xsquared-4x+17=0
How would I solve from this point?

squared= ^2
1. 2(x+3)^2-6x+5 = 0
(x+3)^2 = x^2 + 6x + 9
2x^2 +12x + 18 - 6x +5 = 0
Combine terms.
2x^2 + 6x +17 = 0
Unless you have a typo, I don't agree with your answer.
2. 3x^2 - 6x + 5 = 2x + 2 - 10
Combine terms.
3x^2 - 8x + 2 = 0
Remember that, if you subtract/add from one side, you have to do the same thing to the other side of the equation.
