Final answer to the problem
Step-by-step Solution
Specify the solving method
We can multiply the polynomials $\left(8m^3n^2+6\right)\left(7m^3n^2-9\right)$ 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 ($L\times L$)

$\begin{matrix}(F\times F)\:=\:(8m^3n^2)(7m^3n^2)\\(O\times O)\:=\:(8m^3n^2)(-9)\\(I\times I)\:=\:(6)(7m^3n^2)\\(L\times L)\:=\:(6)(-9)\end{matrix}$
Learn how to solve special products problems step by step online. Expand the expression (8m^3n^2+6)(7m^3n^2-9). We can multiply the polynomials \left(8m^3n^2+6\right)\left(7m^3n^2-9\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. Multiply 6 times -9.
