Find the product of the following binomial: (a2 + bc)(a2 − bc)
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.
\[\left( a^2 + bc \right)\left( a^2 - bc \right)\]
\[ = \left( a^2 \right)^2 - \left( bc \right)^2 \]
\[ = a^4 - b^2 c^2\]
