We need to find thr rate of change (slope) of the line joining these two points ~





Slope of the line (m) joining the two points is 2 ~
The answer is 3.
$6 x 6 = 36
45 - 36 = 9
9 divided by 3 = 3 burgers
Looking at <span>4x3 + x2 – 8x – 2, I see immediately that x^2 can be factored out of the first 2 terms => 4x^2(x+1)
and -2 out of the last 2 terms => -2(4x+1).
Notice how the factor (4x+1) shows up twice.
We can factor this (4x+1) out, obtaining (x^2 - 2) (4x+1). These are the desired factors, found "by grouping."
