D( x )

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

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

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

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

t_1 = x^2

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

7*t_1-3*t_1^2 = 0

DELTA = 7^2-(-3*0*4)

DELTA = 49

DELTA > 0

t_1 = (49^(1/2)-7)/(-3*2) or t_1 = (-49^(1/2)-7)/(-3*2)

t_1 = 0 or t_1 = 7/3

t_1 = 0

x^2+0 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

t_1 = 7/3

x^2-7/3 = 0

1*x^2 = 7/3 // : 1

x^2 = 7/3

x^2 = 7/3 // ^ 1/2

abs(x) = (7/3)^(1/2)

x = (7/3)^(1/2) or x = -(7/3)^(1/2)

x in (-oo:-(7/3)^(1/2)) U (-(7/3)^(1/2):0) U (0:(7/3)^(1/2)) U ((7/3)^(1/2):+oo)

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

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

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

x^2*(7-3*x^2) = 0
