Final answer to the problem
Step-by-step Solution
Specify the solving method
We can multiply the polynomials $\left(5x-8\right)\left(5x+8\right)$ 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 ($L\times L$)

$\begin{matrix}(F\times F)\:=\:(5x)(5x)\\(O\times O)\:=\:(5x)(8)\\(I\times I)\:=\:(-8)(5x)\\(L\times L)\:=\:(-8)(8)\end{matrix}$

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. Multiply -8 times 8.
