Solution for 4x^2-7x+3/4x^2+9x-9 equation: 


x in (-oo:+oo)

4*x^2+(3/4)*x^2-(7*x)+9*x-9 = 0

4*x^2+(3/4)*x^2-7*x+9*x-9 = 0

19/4*x^2+2*x-9 = 0

DELTA = 2^2-(-9*4*19/4)

DELTA = 175

DELTA > 0

x = (175^(1/2)-2)/(2*19/4) or x = (-175^(1/2)-2)/(2*19/4)

x = 2/19*(5*7^(1/2)-2) or x = 2/19*(-5*7^(1/2)-2)

x in { 2/19*(-5*7^(1/2)-2), 2/19*(5*7^(1/2)-2) }
