MARK ME AS BRAINLIEST

Ans: (x + 6)(x - 7)

EXPLANATION:

y = x^2 - x - 42 = (x + P)(x + Q).

p and q have opposite signs. Factor pairs of (-42) --> (-3, 14)(-6, 7). This sum is 1 = -b. The opposite sum gives p and q --> p = 6

and q = -7.

Factored form: y = (x + 6)(x - 7)

y = x^2 - x - 42 = (x + P)(x + Q).

p and q have opposite signs. Factor pairs of (-42) --> (-3, 14)(-6, 7). This sum is 1 = -b. The opposite sum gives p and q --> p = 6

and q = -7.
