Both terms on the left have at least one factor of c, so:

Remember, the distributive property states that a%28b%2Bc%29=ab%2Bac. This can be reversed to get ab%2Bac=a%28b%2Bc%29. In other words, we've factored out the common term "a".


In the case of +c%5E2-7c=0+, the term c%5E2 can be factored to get +c%2Ac-7c=0+

Notice how there's a common factor of "c". So factor this out to get c%28c-7%29=0


Now set each term equal to zero and solve each equation.
