Given:

There is a equation given in the question


3x^2-10=0

Required:

Solve equation by difference of squares formula.

Step-by-step explanation:

First of all divide left side with 3


\begin{gathered} (3x^2-10)/(3)=0 \\ x^2-(10)/(3)=0 \end{gathered}

We have formula for difference of squares


a^2-b^2=(a-b)(a+b)

as formula


\begin{gathered} x^(2)-(10)/(3)=0 \\ (x-\sqrt{(10)/(3)})(x+\sqrt{(10)/(3)}_)=0 \\ x=\pm\sqrt{(10)/(3)} \end{gathered}

Final answer:

Solution of given equation is


x=\operatorname{\pm}\sqrt{(10)/(3)}
