Solution for 4/3x^2-20x=75 equation: 


x in (-oo:+oo)

(4/3)*x^2-(20*x) = 75 // - 75

(4/3)*x^2-(20*x)-75 = 0

(4/3)*x^2-20*x-75 = 0

4/3*x^2-20*x-75 = 0

DELTA = (-20)^2-(-75*4/3*4)

DELTA = 800

DELTA > 0

x = (800^(1/2)+20)/(4/3*2) or x = (20-800^(1/2))/(4/3*2)

x = 3/8*(20*2^(1/2)+20) or x = 3/8*(20-20*2^(1/2))

x in { 3/8*(20-20*2^(1/2)), 3/8*(20*2^(1/2)+20) }
