Answer 2

Hello friends!!

Here is your answer :
$9 {(x + 1)}^{2} + 5 = 149$


Using identity : ( a + b) = a² + b² + 2ab


$9( {x}^{2} + 2x + 1) + 5 = 149$


$9 {x}^{2} + 18x + 9 + 5 = 149$


$9 {x}^{2} + 18x + 14 = 149$


$9 {x}^{2} + 18 = 149 - 14$


$9 {x}^{2} + 18x = 135$


$9 {x}^{2} = 135 - 18x$


${x}^{2} = \frac{135 - 18x}{9}$



$x = \sqrt{ \frac{135 - 18x}{9} }$


Hope it helps you ... ☺️☺️
