$<b><i><font face=Copper black size=4 color=blue>$
Here is your answer

$9 {x}^{2} + - - - - - + \frac{4}{25} \\ \\ = (3x) {}^{2} + - - - - + ( \frac{2}{5} ) {}^{2} \\ \\ = (3x) {}^{2} + 2 \times 3x \times \frac{2}{5} + ( \frac{2}{5} ) {}^{2} \\ \\ = (3x) {}^{2} + \frac{12x}{5} + ( \frac{2}{5} ) {}^{2} \\ \\ = (3x + \frac{2}{5} ) {}^{2}$
Therefore
Space value is
$= \frac{12x}{5}$

$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope\:it\:helps\: you}}}}}}}}}}}}}}}$
