Final Answer
Step-by-step Solution
Specify the solving method
We can multiply the polynomials $\left(7a^2-3b^2\right)\left(7a^2+3b^2\right)$ by using the FOIL method. The acronym F O I L stands for multiplying the terms in each bracket in the following order: First by First ($F\times F$), Outer by Outer ($O\times O$), Inner by Inner ($I\times I$), Last by Last ($L\times L$)

$\begin{matrix}(F\times F)\:=\:(7a^2)(7a^2)\\(O\times O)\:=\:(7a^2)(3b^2)\\(I\times I)\:=\:(-3b^2)(7a^2)\\(L\times L)\:=\:(-3b^2)(3b^2)\end{matrix}$
Learn how to solve special products problems step by step online. Solve the product (7a^2-3b^2)(7a^2+3b^2). We can multiply the polynomials \left(7a^2-3b^2\right)\left(7a^2+3b^2\right) by using the FOIL method. The acronym F O I L stands for multiplying the terms in each bracket in the following order: First by First (F\times F), Outer by Outer (O\times O), Inner by Inner (I\times I), Last by Last (L\times L). Then, combine the four terms in a sum. Substitute the values of the products.
