Solution for 3x^2-13x+4/3x^2-7x-20 equation: 


x in (-oo:+oo)

3*x^2+(4/3)*x^2-(13*x)-(7*x)-20 = 0

3*x^2+(4/3)*x^2-13*x-7*x-20 = 0

13/3*x^2-20*x-20 = 0

DELTA = (-20)^2-(-20*4*13/3)

DELTA = 2240/3

DELTA > 0

x = ((2240/3)^(1/2)+20)/(2*13/3) or x = (20-(2240/3)^(1/2))/(2*13/3)

x = 3/26*((2240/3)^(1/2)+20) or x = 3/26*(20-(2240/3)^(1/2))

x in { 3/26*(20-(2240/3)^(1/2)), 3/26*((2240/3)^(1/2)+20) }
