X^2 + 3x - 28 factors to (X+7)(X-4)
X^2 - 7X + 12 factors to (X-4)(X-3)
Now we see that the equation is [(X+7)(X-4)]/[(X-4)(X-3)]
By dividing the top and bottom by (X-4), we see that the equation equals (X+7)/(X-3).
The answer to your question is 0.125 Hope this helps! God bless
Add -4x and 3x to get -x. then divide -1 on both sides. x=-2
There are numerous ways you can do this, but take a look at the attachment to see how I did it. I hope it answers your question! :)
