Solution for 1/4X^2+3/4-5X-2/3X^2+1/5-2 equation: 


X in (-oo:+oo)

(1/4)*X^2-((2/3)*X^2)-(5*X)+3/4+1/5-2 = 0

(1/4)*X^2+(-2/3)*X^2-5*X+3/4+1/5-2 = 0

-5/12*X^2-5*X-21/20 = 0

DELTA = (-5)^2-(-21/20*(-5/12)*4)

DELTA = 93/4

DELTA > 0

X = ((93/4)^(1/2)+5)/(-5/12*2) or X = (5-(93/4)^(1/2))/(-5/12*2)

X = -6/5*((93/4)^(1/2)+5) or X = -6/5*(5-(93/4)^(1/2))

X in { -6/5*((93/4)^(1/2)+5), -6/5*(5-(93/4)^(1/2)) }
