Points to remember while doing multiplication of algebraic expression.

- Look for the sign of the terms. That is, if both the terms have like signs (\(+,+\)) (or) (\(-,-\)) then the result will have \(+\) sign. If both the terms have unlike signs (\(+,-\)) then the result will have a \(-ve\) sign.
- Multiply the corresponding coefficient of the terms.
- Multiply the variables using the law of exponents.
