${\red{\bold{\text{Given Equation:-}}}}$

⠀⠀7x²=5

${\green{\bold{\text{Now}}}}$

⠀⠀x²=$\frac{5}{7}$

⠀⠀x=${\sqrt{\frac{5}{7}}}$ and -${\sqrt{\frac{5}{7}}}$

We know that the value of x are the roots of a equation.

Now their sum

${\sqrt{\frac{5}{7}}}$+(-${\sqrt{\frac{5}{7}}}$)

=0

$\rule{200}3$

Hope it helps
