Answer:
The factors of x²-64 is equal to (x-8)(x+8).
Step-by-step explanation:
The given expression is:
x²-64
we know that, 8² = 64
So,
(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]
So, the factors of x²-64 i equal to (x-8)(x+8).
To find 10% of 82, you do 82*.1 so 8.2 is taken off the total.
So if we do 82-8.2 you get 73.8 as the sale price
