Use polynomial Identities to factor.

 $8x^6-125y^{15}$  

•  $\left(2x+5y\right)\left(4x^2-10xy+25y^2\right)$  

•  $\left(2x^2+5y^5\right)\left(4x^4-10x^2y^5+25y^{10}\right)$  

•  $\left(2x^2-5y^5\right)\left(4x^4+10x^2y^5+25y^{10}\right)$  

•  $\left(2x-5y\right)\left(4x^2+10xy+25y^2\right)$  

What is the remainder?
 $\frac{2x^3-7x^2+5}{x-3}$

What is the domain for this function?

 $f\left(x\right)=\frac{1}{\sqrt{x+5}}$  *hint type infinity

It takes Jon and Sierra 6 hours to paint one room. If Sierra paints 3 times as fast as Jon, what is the equation we would use to find the time it takes Jon to paint?

• $x+3x=6$

• $\frac{1}{x}+\frac{3}{x}=\frac{1}{6}$

• $\frac{1}{x}+\frac{1}{3x}=\frac{2}{6}$

• $\frac{x}{1}+\frac{x}{3}=\frac{6}{1}$

Find ALL of the x intercepts for f(x).

 $f\left(x\right)=x^3-3x^2+x-3$  

• 3

•  $i$  

• -3

•  $-i$  

•  $-3i$
