what is the factorization of the trinomial below -x^2+x+42 A. (x+6)(x-7) B. -1(x+7)(x+6)C. -1(x-7)(x+6) D. (-x+6)(x+7)

-(x - 7)(x + 6)

Step-by-step explanation:

Step 1: Factor GCF

-1(x² - x - 42)

Step 2: Factor quadratic

-1(x - 7)(x + 6)

C

Step-by-step explanation:

-x²+x+42

=-(x²-x-42)

[7-6=1,7×-6=-42]

=-(x²-(7-6)x-42)

=-(x²-7x+6x-42)

=-[x(x-7)+6(x-7)]

=-(x-7)(x+6)

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

what's that
