First, factor the quadratic trinomial -x² + 10x - 16.

We can rewrite it as -(x² - 10x + 16).

Now factor x² - 10x + 16. We need to find two numbers that multiply to 16 and add up to -10.

The factors of 16 are: 1, 2, 4, 8 and 16.

We need to find two numbers whose sum is -10. The numbers are -2 and -8 becaus...
