Start with the given expression.


Factor 2x%5E2-12x%2B18 to get 2%28x-3%29%28x-3%29.


Factor 4x%5E2-8x-12 to get 4%28x%2B1%29%28x-3%29.


Factor 2x%5E2%2B6x%2B4 to get 2%28x%2B2%29%28x%2B1%29.


Factor x%5E2%2B6x%2B8 to get %28x%2B4%29%28x%2B2%29.


Combine the fractions.


Highlight the common terms.
