Solution for 17/4x^2-16x-12 equation: 


x in (-oo:+oo)

(17/4)*x^2-(16*x)-12 = 0

(17/4)*x^2-16*x-12 = 0

17/4*x^2-16*x-12 = 0

DELTA = (-16)^2-(-12*4*17/4)

DELTA = 460

DELTA > 0

x = (460^(1/2)+16)/(2*17/4) or x = (16-460^(1/2))/(2*17/4)

x = 2/17*(2*115^(1/2)+16) or x = 2/17*(16-2*115^(1/2))

x in { 2/17*(16-2*115^(1/2)), 2/17*(2*115^(1/2)+16) }
