Answer: a^2 - 186a + 8528
Explanation:
To find the value of the expression (-a + 104)(-a + 82), you can use the distributive property, also known as FOIL (First, Outer, Inner, Last). Here's how you do it step by step:
(-a + 104)(-a + 82)
First, multiply the first terms in each set of parentheses:
(-a) * (-a) = a^2
Next, multiply the outer terms:
(-a) * (82) = -82a
Then, multiply the inner terms:
(104) * (-a) = -104a
Finally, multiply the last terms:
(104) * (82) = 8528
Now, combine all the terms:
a^2 - 82a - 104a + 8528
Combine like terms:
a^2 - 186a + 8528
So, the value of the expression (-a + 104)(-a + 82) is a^2 - 186a + 8528.
