Solution for 7t^2-10t-8/7t-3 equation: 


t in (-oo:+oo)

7*t^2-(10*t)-((8/7)*t)-3 = 0

7*t^2-10*t+(-8/7)*t-3 = 0

7*t^2-78/7*t-3 = 0

DELTA = (-78/7)^2-(-3*4*7)

DELTA = 10200/49

DELTA > 0

t = ((10200/49)^(1/2)+78/7)/(2*7) or t = (78/7-(10200/49)^(1/2))/(2*7)

t = ((10200/49)^(1/2)+78/7)/14 or t = (78/7-(10200/49)^(1/2))/14

t in { (78/7-(10200/49)^(1/2))/14, ((10200/49)^(1/2)+78/7)/14 }
