Question

What is one of the factors of z2 - 162 Make sure to put parentheses around your answer, for example: (x+1)

Answer 1

The expression to factor is:

`z^2-16^2`

This matches with the general expression of:

`a^2-b^2`

Which can be factored as:

`a^2-b^2=(a+b)(a-b)`

Now, we can factor our expression as:

`z^2-16^2=(z-16)(z+16)`

These 2 factors multiplied together, gives us the expression.

So, one of the factors would be:

`(z-16)`
