Solution for 8x^2-6x-9/2x-3 equation: 


x in (-oo:+oo)

8*x^2-(6*x)-((9/2)*x)-3 = 0

8*x^2-6*x+(-9/2)*x-3 = 0

8*x^2-21/2*x-3 = 0

DELTA = (-21/2)^2-(-3*4*8)

DELTA = 825/4

DELTA > 0

x = ((825/4)^(1/2)+21/2)/(2*8) or x = (21/2-(825/4)^(1/2))/(2*8)

x = ((825/4)^(1/2)+21/2)/16 or x = (21/2-(825/4)^(1/2))/16

x in { (21/2-(825/4)^(1/2))/16, ((825/4)^(1/2)+21/2)/16 }
