Solution for 15-6*x/4-x^2 equation: 


x in (-oo:+oo)

15-x^2-((6*x)/4) = 0

(-3/2)*x-x^2+15 = 0

15-x^2-3/2*x = 0

DELTA = (-3/2)^2-(-1*4*15)

DELTA = 249/4

DELTA > 0

x = ((249/4)^(1/2)+3/2)/(-1*2) or x = (3/2-(249/4)^(1/2))/(-1*2)

x = ((249/4)^(1/2)+3/2)/(-2) or x = (3/2-(249/4)^(1/2))/(-2)

x in { ((249/4)^(1/2)+3/2)/(-2), (3/2-(249/4)^(1/2))/(-2) }
