Complete Factorization : a polynomial is factored completely if it can't be broken down any further.
Example: $5x^5-5x y^4$
Factoring Strategy
Examples: Factor the following polynomial expressions.
$y^3 +7 y^2 -y - 7$
$245 s^3 \alpha-20 s \alpha^3$
$2 z p^2-2 z c^4$
$36t^2ā25c^2ā40cā16$
$u^2+2u+1+u \gamma+\gamma$
