Question

Find the positive answer to this equation 0=1/3x^2-3

Answer 1

Answer:
`x=3`

Subtract 1/3x² from both sides

`0-(1)/(3) x^2=(1)/(3) x^2-3-(1)/(3) x^2`

`-(1)/(3) x^2=-3`

Divide both sides by -1/3

`-(1)/(3) x^2/(1)/(3) =-3/-(1)/(3)`

`x^2=9`

Take square root

x=±√9

`x=3`

Answer 2

3

Explanation:

the positive answer for this equation is

x=(3,-3)

so the positive answer is:3
