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

$\begin{matrix}(F\times F)\:=\:(-3x)(y)\\(O\times O)\:=\:(-3x)(3x)\\(I\times I)\:=\:(y)(y)\\(L\times L)\:=\:(y)(3x)\end{matrix}$
Learn how to solve special products problems step by step online. Solve the product (-3x+y)(y+3x). We can multiply the polynomials \left(-3x+y\right)\left(y+3x\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. When multiplying two powers that have the same base (y), you can add the exponents.
