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


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

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

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

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

7/4*x^1+2*x^-1+12*x^0 = 0

(7/4*x^2+12*x^1+2*x^0)/(x^1) = 0 // * x^2

x^1*(7/4*x^2+12*x^1+2*x^0) = 0

x^1

(7/4)*x^2+12*x+2 = 0

(7/4)*x^2+12*x+2 = 0

DELTA = 12^2-(2*4*(7/4))

DELTA = 130

DELTA > 0

x = (130^(1/2)-12)/(2*(7/4)) or x = (-130^(1/2)-12)/(2*(7/4))

x = 2/7*(130^(1/2)-12) or x = -2/7*(130^(1/2)+12)

x in { -2/7*(130^(1/2)+12), 2/7*(130^(1/2)-12)}

x in { -2/7*(130^(1/2)+12), 2/7*(130^(1/2)-12) }
