Solution for 4t^2/5=9t/5+11/10 equation: 


t in (-oo:+oo)

(4*t^2)/5 = (9*t)/5+11/10 // - (9*t)/5+11/10

(4*t^2)/5-((9*t)/5)-(11/10) = 0

(4*t^2)/5+(-9/5)*t-11/10 = 0

4/5*t^2-9/5*t-11/10 = 0

DELTA = (-9/5)^2-(-11/10*4/5*4)

DELTA = 169/25

DELTA > 0

t = ((169/25)^(1/2)+9/5)/(4/5*2) or t = (9/5-(169/25)^(1/2))/(4/5*2)

t = 11/4 or t = -1/2

t in { -1/2, 11/4 }
