MR. Organic Chemistry Tutor, thank you for another well explained video/lecture on The Basic Introduction to Rational Expression in Algebra One/Two. Rational expression is easy to deal with as long as you do not divide by zero.
This is really useful for me now I won't have any problems in algebra once my online class begins so thank you | | V this is how many people agree with me Edit:Yay in third in the comments
1:46 why did you switch the signs? I want to know so i will know when to apply that technique when dealing with a probem like this. Would appreciate it if anyone replied.
The top term was originally (5-x) but the bottom term was (x-5), so if you would take out a "-", the top term would become -(-5+x) aka -(x-5) and therefore the top and bottom could cancel.
Thank you very much. Iam improving in maths by seeing ur vedios. Iam studing in 8th class. So please i request u to bring some vedios of 8th class Maths
Sirr I don't understand the last part why couldn't you use negative and a positive sign to equal 1 why did it both have to be positive or negative in order to factor it out I'm confused sir
I know this reply is too late to matter, but it's because the numbers have to also be able to multiply to the number on the right, and if only one is a negative then it would multiply to a negative number instead.
