Solution for 2a^2-5a-3/2a^2-12+18 equation: 


a in (-oo:+oo)

2*a^2-((3/2)*a^2)-(5*a)-12+18 = 0

2*a^2+(-3/2)*a^2-5*a-12+18 = 0

1/2*a^2-5*a+6 = 0

DELTA = (-5)^2-(1/2*4*6)

DELTA = 13

DELTA > 0

a = (13^(1/2)+5)/(1/2*2) or a = (5-13^(1/2))/(1/2*2)

a = 13^(1/2)+5 or a = 5-13^(1/2)

a in { 5-13^(1/2), 13^(1/2)+5 }
