Solution for 3/5m^2+6m=-21/5 equation: 


m in (-oo:+oo)

(3/5)*m^2+6*m = -21/5 // + -21/5

(3/5)*m^2+6*m-(-21/5) = 0

(3/5)*m^2+6*m+21/5 = 0

3/5*m^2+6*m+21/5 = 0

DELTA = 6^2-(3/5*4*21/5)

DELTA = 648/25

DELTA > 0

m = ((648/25)^(1/2)-6)/(3/5*2) or m = (-(648/25)^(1/2)-6)/(3/5*2)

m = 5/6*((648/25)^(1/2)-6) or m = -5/6*((648/25)^(1/2)+6)
