So what is your question here?
<h2><em>6.96cm^2.</em></h2><h2><em>5.8 x 1.2 = 6.96cm^2.</em></h2>
314.16 yards^2 for the Area
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
