x in (-oo:+oo)
4*(2*x-1)*(3-(5*x)) = 3/4-(3*x) // - 3/4-(3*x)
4*(2*x-1)*(3-(5*x))+3*x-(3/4) = 0
4*(2*x-1)*(3-5*x)+3*x-3/4 = 0
(4^2*(2*x-1)*(3-5*x))/4+(3*4*x)/4-3/4 = 0
4^2*(2*x-1)*(3-5*x)+3*4*x-3 = 0
188*x-160*x^2-48-3 = 0
188*x-160*x^2-51 = 0
188*x-160*x^2-51 = 0
188*x-160*x^2-51 = 0
DELTA = 188^2-(-160*(-51)*4)
DELTA = 2704
DELTA > 0
x = (2704^(1/2)-188)/(-160*2) or x = (-2704^(1/2)-188)/(-160*2)
x = 17/40 or x = 3/4
(x-17/40)*(x-3/4) = 0
((x-17/40)*(x-3/4))/4 = 0
((x-17/40)*(x-3/4))/4 = 0 // * 4
(x-17/40)*(x-3/4) = 0
( x-17/40 )
x-17/40 = 0 // + 17/40
x = 17/40
( x-3/4 )
x-3/4 = 0 // + 3/4
x = 3/4
