What is the first step when factoring polynomials?

• Find the GCF
• List all the terms
• Make a triangle
• Write the answer

Solve by factoring.
 $x^2-8x-9\ =\ 0$  

•  $\left(x-9\right)\left(x+1\right)$  

•  $\left(x-9\right)^2$  

•  $\left(x\ +9\right)\left(x-1\right)$  

•  $\left(x+1\right)^2$
