Solution for 4x^2-15x+9/4x^2+13x-12 equation: 


x in (-oo:+oo)

4*x^2+(9/4)*x^2-(15*x)+13*x-12 = 0

4*x^2+(9/4)*x^2-15*x+13*x-12 = 0

25/4*x^2-2*x-12 = 0

DELTA = (-2)^2-(-12*4*25/4)

DELTA = 304

DELTA > 0

x = (304^(1/2)+2)/(2*25/4) or x = (2-304^(1/2))/(2*25/4)

x = 2/25*(4*19^(1/2)+2) or x = 2/25*(2-4*19^(1/2))

x in { 2/25*(2-4*19^(1/2)), 2/25*(4*19^(1/2)+2) }
