Show me how you did one of them, and I will evaluate your solution.
BTW, with the coefficients of your questions, the method of completing the square would be my last choice of the 3 main methods of solving quadratic equations.
Solve each equation by completing the square.
-36x=8x^2+28
-8x^2-3x=-5
5x^2-x-6=0
6x^2-24x-30=0
7x^2+8x-12=0
-10x^2 -9x+1=0
5x^2-x=4
-11x^2-8x=-7x-10
-3 1/3x^2+ 10x -27 1/2= -231/3
