If `3x+5y=11` and `xy=2,` find the value of `9x^2+25 y^2`

Explanation

To find the value of \( 9x^2 + 25y^2 \) given the equations \( 3x + 5y = 11 \) and \( xy = 2 \), we can follow these steps:

### Step 1: Square the first equation
We start with the equation:
\[ 3x + 5y = 11 \]
Now, we will square both sides:
