No.108 Distributive Property
POINT
Use the distributive property to remove parentheses. When dividing by a fraction, multiply by its reciprocal.
Simplify the following expressions.
Example
\(2(4a-3b)\)
\((6a-12b)\div3\)
\((8a+6b)\div\frac{2}{5}\)
① \(8a-6b\)
② \(2a-4b\)
③ \(20a+15b\)
② \(2a-4b\)
③ \(20a+15b\)
Try it yourself.
