Solution for 4x2/3-7x1/3-2=0 equation: 


x in (-oo:+oo)

(4*x^2)/3-((7*x^1)/3)-2 = 0

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

4/3*x^2-7/3*x-2 = 0

DELTA = (-7/3)^2-(-2*4/3*4)

DELTA = 145/9

DELTA > 0

x = ((145/9)^(1/2)+7/3)/(4/3*2) or x = (7/3-(145/9)^(1/2))/(4/3*2)

x = 3/8*((145/9)^(1/2)+7/3) or x = 3/8*(7/3-(145/9)^(1/2))

x in { 3/8*(7/3-(145/9)^(1/2)), 3/8*((145/9)^(1/2)+7/3) }
