Step-by-step Solution
Specify the solving method
We can multiply the polynomials $\left(x-3\right)\left(x-4\right)+\left(x-3\right)\left(x+4\right)$ 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 ($L\times L$)

We can multiply the polynomials \left(x-3\right)\left(x-4\right)+\left(x-3\right)\left(x+4\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. We can multiply the polynomials x\cdot x-4x-3x-3\cdot -4+\left(x-3\right)\left(x+4\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).
