Simplify Complex Fractions 2

[@jimpsky]

Really well done, perfect pace, thanks a lot!!!

At 7:49 why did you get positive 4 instead of negative?

[@YourMathGal]

In the big denominator, after multiplying (x+2)(x-2), it cancels the den. x^2-4, so only the numerator is still there, which is +4, not -4.

You've saved my life!

Thanks for covering both methods in one video.

[@garysellars8914]

Great videos. So well explained.

5:38 the 2 in the numerator and the 4 in the denominator can be divide into 2 right? so that the answer is x/2-x

[@adamdintelman2067]

This was extremely helpful thank you so much!!!!!!!!

[@aljoyaeron]

Life saver! :) Thanks CoolMathGal!

I got the same answer but I reduced the answer to 1+X/2-X, is it possible to reduce? Or am I breaking some rule?

[@yourdancegal]

No. You can only cancel factors. Put a parentheses around the numerator and denominator. You can only cancel that exact factor...not part of a factor. Think about if you had 2 + 3 over 4 - 3. That is 5/1 or 5. You couldn't cancel to get 3/2-3. either. All I did was put in 3 for x to show it wouldn't work if you canceled. See my videos on simplifying rational expressions for more info on this.

how is it both xsquared to both

[@frenchie6800]

In second example why didn't you use X2 as LCD, but instead you used X? In first example, which was similar to second example, you decided to use X2 as LCD and the X. Please advise. Thanks.

THANK YOU, THANK YOU, THANK YOU!!!!

[@Artgamer270TM]

how about an algebraic expressions is divided over a fraction
i.e.
2(2x+3) / (2x-3)/(x^2+4)
