Question 1052979: Solve for m: 4m^2-5m=6
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! 4m^2-5m = 6
4m^2-5m-6 = 0
factor this equation:
(m-2)(4m+3)
m-2 = 0 or 4m+3 = 0
m = 2 or m = -3/4 = -0.75
So, you have two possible answers. To find your answer substitute for m, I'm going to start with 0:
4(0)^2-5(0) = 6 this is false, so let's try -0.75
4(-0.75)^2-5(-0.75) = 6
2.25+375 = 6 correct
