Mathematics

X^2 + 2x -8
The factors of 8 are 2 and 4, and to get 2x we need 2 and 4 to either add up to or subtract to result in 2.
4 - 2 = 2. We also know this is right because 4 x -2 = -8. So the answer is:
(x + 4)(x - 2)

Help plz ? Enter the slope of the line
Dmitrij [34]
(-2,4), (2,5)

Slope equation : (y₂-y₁) / (x₂-x₁)

Plug in the values.

m = slope

m = (5-4) / (2 + 2)

Simplify.

m = 1/4

So, your slope is 1/4
