x in (-oo:+oo)

2*x^2-(11*x)-((63/2)*x)+7 = 0

2*x^2-11*x+(-63/2)*x+7 = 0

2*x^2-85/2*x+7 = 0

DELTA = (-85/2)^2-(2*4*7)

DELTA = 7001/4

DELTA > 0

x = ((7001/4)^(1/2)+85/2)/(2*2) or x = (85/2-(7001/4)^(1/2))/(2*2)

x = ((7001/4)^(1/2)+85/2)/4 or x = (85/2-(7001/4)^(1/2))/4

x in { (85/2-(7001/4)^(1/2))/4, ((7001/4)^(1/2)+85/2)/4 }
