Explanation:

Add 7 to both sides of the equation

3x^2=7

Divide each term by 3 and simplify

x^2 = 7/3

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x=±√7/3

The complete solution is the result of both the positive and negative portions of the solution.

x=√21/3 , −√21/3

The result can be shown in multiple forms.

Exact Form: x = √21/3 , −√21/3

Decimal Form:

x=1.52752523… , −1.52752523....
