-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

**drwls**, Sunday, November 11, 2007 at 8:50am36x = 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 = (81-56)/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
