The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²

<h3>What is an Expression ?</h3>

An expression is a mathematical statement which has variables , constants and mathematical operators simultaneously.

The expression given in the question is

(3x+6y)(3x+6y) and (4x+9y)(4x+9y)

the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y)

(4x+9y)(4x+9y) - (3x+6y)(3x+6y)

16 x² + 36xy+36xy +81y²-9x²-18x -18x -36y²

7x² +36xy+45y²

Therefore in simplest term , The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²
