Ok 2(4x9) ................................
Move the 6 to the other side:
2x^2 +x+6,
(x-3) (x+4)
x=3 and x=-4
The slope formula is the changes of two y-values over/to the changes of two x-values.

Substitute two given points in the formula to find the slope. The m-term represents the slope from y = mx+b.

Answer
Hope this helps and let me know if you have any doubts!
Answer:
Option C
Step-by-step explanation:
you cancel the whole parentheses.
So you know, x+6 can't equal to 0.
that's why there is a choice that is all real numbers but not -6.
