To solve this, we will need to distribute out the values in parentheses. To do this, we can use a series called the FOIL method, where we multiply the first terms, outside terms, inside terms, and last terms.
(m-7)(9m-1) 9m²-m-63m+7 9m²-64m+7
Using the math above, we can see that when we multiply these values, the answer is 9m²-64m+7.
