Factor the expression completely. $$x^{2}\left(x^{2}-1\right)-9\left(x^{2}-1\right)$$
Factor the expression completely. $$2 x^{3}+4 x^{2}+x+2$$
A square field in a certain state park is mowed around the edges every week. The rest of the field is kept unmowed to serve as a habitat for birds and small animals (see the figure). The field measures \(b\) feet by \(b\) feet, and the mowed strip is \(x\) feet wide. (a) Explain why the area of the mowed portion is \(b^{2}-(b-2 x)^{2}\) (b) Factor the expression in (a) to show that the area of the mowed portion is also \(4 x(b-x)\) CAN'T COPY THE GRAPH
