Final answer to the problem
Step-by-step Solution
Specify the solving method
We can multiply the polynomials $\left(-4-4x^2\right)\left(25x^2+50x+24\right)$ 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 ($L\times L$)

$\begin{matrix}(F\times F)\:=\:(-4x^2)(25x^2)\\(O\times O)\:=\:(-4x^2)(50x+24)\\(I\times I)\:=\:(-4)(25x^2)\\(L\times L)\:=\:(-4)(50x+24)\end{matrix}$
Learn how to solve special products problems step by step online. Expand the expression (-4-4x^2)(25x^2+50x+24). We can multiply the polynomials \left(-4-4x^2\right)\left(25x^2+50x+24\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. Solve the product -4\left(50x+24\right).
