Question 888527: X+1 - 2x+1 = 5-x^2
___ _____ ______
X+5 x-2 x^2+3x-10
I need help solving this equation. The equations are suppose to be division. I couldn't get the lines directly under the first line of number. Thank you.

You can put this solution on YOUR website!
X+1 - 2x+1 = 5-x^2
___ _____ ______
X+5 x-2 x^2+3x-10

Not a good way to write it.

Try it in pure text this way:
(x+1)/(x+5)-(2x+1)/(x-2)=(5-x^2)/(x^2+3-10)

Rendering tags will make it show like:
%28x%2B1%29%2F%28x%2B5%29-%282x%2B1%29%2F%28x-2%29=%285-x%5E2%29%2F%28x%5E2%2B3-10%29

Can you factor the numerator of the right-hand member?


The lowest (or simplest) common denominator is %28x%2B5%29%28x-2%29. Multiply the left member AND the right member this %28x%2B5%29%28x-2%29 and this will help in simplifying the equation. That result omitting the actual step gives this:

highlight_green%28%28x%2B1%29%28x-2%29-%282x%2B1%29%28x%2B5%29=5-x%5E2%29
Continuing from there,
x%5E2-x-2-%282x%5E2%2B11x%2B5%29=5-x%5E2
x%5E2-x-2-2x%5E2-11x-5=5-x%5E2
-x%5E2-12x-7=5-x%5E2
-12x-7=5
12x%2B7=-5
12x=-5-7
12x=-12
highlight%28x=-1%29
