We can multiply the polynomials $\left(-\sin\left(x\right)+\cos\left(x\right)+2\right)\left(-\cos\left(x\right)-\sin\left(x\right)\right)$ 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 ($L\times L$)

$\begin{matrix}(F\times F)\:=\:(-\sin\left(x\right))(-\cos\left(x\right))\\(O\times O)\:=\:(-\sin\left(x\right))(-\sin\left(x\right))\\(I\times I)\:=\:(\cos\left(x\right)+2)(-\cos\left(x\right))\\(L\times L)\:=\:(\cos\left(x\right)+2)(-\sin\left(x\right))\end{matrix}$
Learn how to solve simplify trigonometric expressions problems step by step online. Expand and simplify the trigonometric expression (-sin(x)+cos(x)+2)(-cos(x)-sin(x)). We can multiply the polynomials \left(-\sin\left(x\right)+\cos\left(x\right)+2\right)\left(-\cos\left(x\right)-\sin\left(x\right)\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. Multiplying polynomials -\cos\left(x\right) and \cos\left(x\right)+2.
