Solution for (4t^2/5)=(3t/5)+(27/10) equation: 


t in (-oo:+oo)

(4*t^2)/5 = (3*t)/5+27/10 // - (3*t)/5+27/10

(4*t^2)/5-((3*t)/5)-(27/10) = 0

(4*t^2)/5+(-3/5)*t-27/10 = 0

4/5*t^2-3/5*t-27/10 = 0

DELTA = (-3/5)^2-(-27/10*4/5*4)

DELTA = 9

DELTA > 0

t = (9^(1/2)+3/5)/(4/5*2) or t = (3/5-9^(1/2))/(4/5*2)

t = 9/4 or t = -3/2

t in { -3/2, 9/4 }
