Solve each equation by completing the square.
36x=8x^2+28
8x^23x=5
5x^2x6=0
6x^224x30=0
7x^2+8x12=0
10x^2 9x+1=0
5x^2x=4
11x^28x=7x10
3 1/3x^2+ 10x 27 1/2= 231/3

#7) 5x^2x=4 is x=1

36x = 8x^2 +28
8 x^2 36x +28 = 0
x^2 (9/2)x + 7/2 = 0
(x  9/4)^2 +7/2  81/16 = 0
(x  9/4)^2 = (8156)/16 = 25/16
x  9/4 = + or  5/4
x = 1 or 7/2
I'll be glad to check your work on the other ones
