You can  put this solution on YOUR website! m^2-1/2m=7/2 
b is -1/2 
take half and square it to give you 1/16 
add to both sides: 
m^2-1/2m + 1/16 = 7/2 + 1/16 
m^2-1/2m + 1/16 = 56/16 + 1/16 
m^2-1/2m + 1/16 = 57/16 
(m - 1/4)^2 = 57/16 
take the square root of both sides: 
m - 1/4 = sqrt(57/16) 
m - 1/4 = sqrt(57)/4 
m = sqrt(57)/4 + 1/4 
m = (1 + sqrt(57))/4
