Solution for 4a^2+4a+1/2a^2+3a+1 equation: 


a in (-oo:+oo)

4*a^2+(1/2)*a^2+4*a+3*a+1 = 0

9/2*a^2+7*a+1 = 0

DELTA = 7^2-(1*4*9/2)

DELTA = 31

DELTA > 0

a = (31^(1/2)-7)/(2*9/2) or a = (-31^(1/2)-7)/(2*9/2)

a = (31^(1/2)-7)/9 or a = (-(31^(1/2)+7))/9

a in { (-(31^(1/2)+7))/9, (31^(1/2)-7)/9 }
