m^2-9/2m=3/2

**Henry**, Monday, July 12, 2010 at 10:56pmm^2 -9/2m = 3/2.

m^2 -9/2m + (9/4)^2 = 3/2 + (9/4)^2

m^2 - 9/2m +(9/4)^2 = 24/16 + 81/16

m^2 -9/2m + (9/4)^2 = 105/16

(m - 9/4)^2 = 105/16

Take sqrt of both sides:

m - 9/4 = (sqrt105)/4

m = 9/4 + (sqrt105)/4 = (9 +- sqrt105)/4

m = 4.8, and -0.31.
