Question

How do you solve `(x - 11)(x + 5) = 0`?

Answer 1

`x=11` or `x=-5`

Explanation:

The product `(x-11)(x+5)` will only be zero when at least one of the factors `(x-11)` or `(x+5)` is zero. Conversely, if either of these factors is zero then their product will be zero.

So the solutions are `x=11` or `x=-5`
