Question
Find the product of the following binomial: (a + 2b)(a − 2b)
Advertisements
Solution
We will use the identity
\[\left( a + b \right)\left( a - b \right) = a^2 - b^2\] in the given expression to find the product.
\[\left( a + 2b \right)\left( a - 2b \right)\]
\[ = a^2 - \left( 2b \right)^2 \]
\[ = a^2 - 4 b^2\]
