1. 2(x+3)squared6x+5=0
Answer= 2xsquared+6x+23=0
2. 3xsquared6x+5=2(x+1)10
Answer= 3xsquared4x+17=0
How would I solve from this point?

squared= ^2

1. 2(x+3)^26x+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.
