What is the factorization of the trinomial below?

-x2 + x + 42

- (x + 6) (x - 7)

Step-by-step explanation:

The expression that we have can also be expressed in the following way:

- (x ^ 2 - x - 42)

Now to factorize we must find two numbers that multiplied by - 42 and the sum of these numbers by - 1.

these numbers are: - 7 and 6

-7 * 6 = - 42

-7 + 6 = - 1

Thus:

- (x + 6) (x - 7)
