IM Alg2.2.24 Practice: Polynomial Identities (Part 2)

Is [math]a^6+b^6=(a^2+b^2)(a^4-a^2b^2+b^4)[/math] an identity? Explain or show your reasoning.
Match each lettered expression with the number of an expression equivalent to it.
Let [math](x^2+5x+4)(x+2)=A(x+1)[/math]. If this is an identity, what is a possible expression for [math]A[/math]?
What are the points of intersection between the graphs of the functions [math]f(x)=(x+6)(2x+1)[/math] and [math]g(x)=2x+1[/math]?
[size=150]Identify all values of [math]x[/math] that make the equation true.[/size][br][br][math]\frac{x+5}{x+11}=\frac{1}{x+5}[/math]
[math]\frac{2x-3}{x}=\frac{14}{x+5}[/math]
