Answer 1

Given:

The expression is,

`45x^2y^2+18x^3`

Simplify the expression,

`\begin{gathered} 45x^2y^2+18x^3=9*5x^2y^2+9*2x^3 \\ =(9*5* x^2* y^2)+(9*2* x^2* x) \\ \text{Take 9x}^2\text{ common from both the brackets,} \\ =9* x^2\lbrack5* y^2\rbrack+9* x^2\lbrack2x\rbrack \\ =9x^2(5y^2+2x) \end{gathered}`

Answer:

`9x^2(5y^2+2x)`
