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?

  • math check my answers -

    squared= ^2

  • math check my answers -

    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.
