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


x in (-oo:+oo)

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

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

t_1 = x^2

2*t_1^2+3*t_1^1-7 = 0

2*t_1^2+3*t_1-7 = 0

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

DELTA = 65

DELTA > 0

t_1 = (65^(1/2)-3)/(2*2) or t_1 = (-65^(1/2)-3)/(2*2)

t_1 = (65^(1/2)-3)/4 or t_1 = (-(65^(1/2)+3))/4

t_1 = (-(65^(1/2)+3))/4

x^2-((-(65^(1/2)+3))/4) = 0

x^2+(1/4)*(65^(1/2)+3) = 0

1*x^2 = -(1/4*(65^(1/2)+3)) // : 1

x^2 = -1/4*(65^(1/2)+3)

t_1 = (65^(1/2)-3)/4

x^2-((65^(1/2)-3)/4) = 0

1*x^2 = (65^(1/2)-3)/4 // : 1

x^2 = (65^(1/2)-3)/4

x^2 = (65^(1/2)-3)/4 // ^ 1/2

abs(x) = ((65^(1/2)-3)^(1/2))/2

x = ((65^(1/2)-3)^(1/2))/2 or x = -(((65^(1/2)-3)^(1/2))/2)

x in { ((65^(1/2)-3)^(1/2))/2, -(((65^(1/2)-3)^(1/2))/2) }
