<span>To simplify the expression, we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We get the factors of 4 equations present in the expression. 
</span><span>x^2+x-12 = {3,-4}
</span><span>x^2-x-20 = {5,-4}
</span><span>3x^2-24+45 = {5,3}
</span><span>12x^2-48x-60 = {5,-1}</span> 

hence we cancel 5 and from numerator and denominator.

the answer is  (x+4)^2/ (x-5)*(x+1)

Find the slope of the line that contains the points (6, -2) and (-3, 7).
Orlov [11]
The way I used to think to figure this out is to remember that a slope is "rise over run" or y over x (y/x). You'll want to find the change of y and the change of x. There is a change of -9 between 6 and -3. The change between -2 and 7 is 9 too. 9/-9 equals -1. So the slope is -1.
