Solution for 10t+15=4t^2/5 equation: 


t in (-oo:+oo)

10*t+15 = (4*t^2)/5 // - (4*t^2)/5

10*t-((4*t^2)/5)+15 = 0

(-4/5)*t^2+10*t+15 = 0

10*t-4/5*t^2+15 = 0

DELTA = 10^2-(-4/5*4*15)

DELTA = 148

DELTA > 0

t = (148^(1/2)-10)/(-4/5*2) or t = (-148^(1/2)-10)/(-4/5*2)

t = -5/8*(2*37^(1/2)-10) or t = -5/8*(-2*37^(1/2)-10)

t in { -5/8*(2*37^(1/2)-10), -5/8*(-2*37^(1/2)-10) }
