How do you solve #-2/(x-1)=(x-8)/(x+1)#?
The answer is
We see that the equation is a proportion, so we can cross-multiply to start off. Cross-multiplying, the equation becomes:
We can then distribute the -2 on the left side, while multiplying out the right-hand side using FOIL (or any method you learned).
Now, we can factor the equation to get the zeroes of the equation or the values for
To get the zeroes, we see that if
