Answer 1

Answer:

$= (3x)^{2} - 2*3x*\frac{3}{5y}+(\frac{3}{5y})^{2} +2*3x*\frac{3}{5y}-\frac{18x}{5y}\\=(3x-\frac{3}{5y})^{2} +\frac{18x}{5y}- \frac{18x}{5y}\\=(3x-\frac{3}{5y})^{2}$

Answer 2

Question:-

form a whole square from the equation:-

9x² + 9/25y² - 18x/5y.

Correct answer:-

Answer:

\begin{gathered}= (3x)^{2} - 2*3x*\frac{3}{5y}+(\frac{3}{5y})^{2} +2*3x*\frac{3}{5y}-\frac{18x}{5y}\\=(3x-\frac{3}{5y})^{2} +\frac{18x}{5y}- \frac{18x}{5y}\\=(3x-\frac{3}{5y})^{2}\end{gathered}
