Answer:
3
Step-by-step explanation:
the positive answer for this equation is
x=(3,-3)
so the positive answer is:3
Answer: [tex]x=3[/tex]
Subtract 1/3x² from both sides
[tex]0-\frac{1}{3} x^2=\frac{1}{3} x^2-3-\frac{1}{3} x^2[/tex]
[tex]-\frac{1}{3} x^2=-3[/tex]
Divide both sides by -1/3
[tex]-\frac{1}{3} x^2/\frac{1}{3} =-3/-\frac{1}{3}[/tex]
[tex]x^2=9[/tex]
Take square root
x=±√9
[tex]x=3[/tex]
