Question

if x is equal to 2 by 3 + root 7 find x minus 3 power 2​

Answer 1

Here's the Answer :

$x = \frac{2}{3} + \sqrt{7} \\ \implies \: x = \frac{2 + 3 \sqrt{7} }{3} \\ \\ now \\x - {3}^{2} \\ = \frac{2 + 3 \sqrt{7} }{3} - 9 \\ = \frac{2 + 3 \sqrt{7} - 27}{3} \\ = \frac{3 \sqrt{7} - 25}{3}$

Answer 2

Here's the Answer :

\begin{lgathered}x = \frac{2}{3} + \sqrt{7} \\ \implies \: x = \frac{2 + 3 \sqrt{7} }{3} \\ \\ now \\x - {3}^{2} \\ = \frac{2 + 3 \sqrt{7} }{3} - 9 \\ = \frac{2 + 3 \sqrt{7} - 27}{3} \\ = \frac{3 \sqrt{7} - 25}{3}\end{lgathered}
