Do you want to factor?


2x%28x-7%29%2B3%28x-7%29 Start with the given expression.


%282x%2B3%29%28x-7%29 Factor out the GCF x-7


So 2x%28x-7%29%2B3%28x-7%29 factors to %282x%2B3%29%28x-7%29


---------------------------------------------------------------

Or....

Do you want to expand?


2x%28x-7%29%2B3%28x-7%29 Start with the given expression.


2x%28x%29-2x%287%29%2B3%28x%29-3%287%29 Distribute


2x%5E2-14x%2B3x-21 Multiply


2x%5E2-11x-21 Combine like terms.


So 2x%28x-7%29%2B3%28x-7%29 expands to 2x%5E2-11x-21
