Question

How do you multiply `(k - 2)(k - 1)`?

Answer 1

`k^2 - 3k + 2`

Explanation:

Use cross multiplication to multiply each term in the parenthesis on the left by each term within the parenthesis on the left:

`(k*k - (1*k) - (2*k) + 2`

`k^2 - 1k - 2k + 2`

Now combine like terms:

`k^2 - 3k + 2`
