Solution for 15x^2-110x/16=5 equation: 


x in (-oo:+oo)

15*x^2-((110*x)/16) = 5 // - 5

15*x^2-((110*x)/16)-5 = 0

15*x^2+(-55/8)*x-5 = 0

15*x^2-55/8*x-5 = 0

DELTA = (-55/8)^2-(-5*4*15)

DELTA = 22225/64

DELTA > 0

x = ((22225/64)^(1/2)+55/8)/(2*15) or x = (55/8-(22225/64)^(1/2))/(2*15)

x = ((22225/64)^(1/2)+55/8)/30 or x = (55/8-(22225/64)^(1/2))/30

x in { (55/8-(22225/64)^(1/2))/30, ((22225/64)^(1/2)+55/8)/30 }
