Answer:

-(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)
