Solution for 2y^2-9y-5/2y^2-11y-6 equation: 


y in (-oo:+oo)

2*y^2-((5/2)*y^2)-(9*y)-(11*y)-6 = 0

2*y^2+(-5/2)*y^2-9*y-11*y-6 = 0

-1/2*y^2-20*y-6 = 0

DELTA = (-20)^2-(-6*(-1/2)*4)

DELTA = 388

DELTA > 0

y = (388^(1/2)+20)/(-1/2*2) or y = (20-388^(1/2))/(-1/2*2)

y = -(2*97^(1/2)+20) or y = -(20-2*97^(1/2))

y in { -(2*97^(1/2)+20), -(20-2*97^(1/2)) }
