Learn how to solve a rational equation and check your solutions

👉 Learn how to solve rational equations. A rational expression is an expression in the form of a fraction where the numerator and/or the denominator are/is an algebraic expression. There are many ways to solve rational expressions, one of the ways is by multiplying all the individual rational expressions by the lowest common multiply (LCM) of the denominators. This eliminates the denominators and then we can evaluate the resulting equation accordingly.

It is very helpful to check your results by substituting them into the original equation to see if they are true. This also helps to identify the extraneous solutions. An extraneous solution is a solution that is obtained during the course of solving an equation but which does not hold true for the original equation.

Your videos are great. I've been going back and reviewing high school algebra and pre-clac and it helps so much in my college classes to stay fresh on this stuff. You are an awesome teacher and keep up the good work.

They can actually cross multiply the left side of the equation as well

Your good teacher mr Brian your definitely helping me ❤️❤️

2x^2-6x+x-1=2
2x^2-5x-3=0
2x^2+x-6x-3=0
2x(x+1)-3(x+1)
(2x-3)(x+1)
2x=3 dan x=-1
x=3/2 dan x=-1

how to get its range Sir? hope you'll replyyy

[tomkuntz]

FYI. The equation in the thumbnail is different from the equation you actually solve. In the thumbnail, the left side of the equation is (2x/x-1 ) - (1/x-3). The left side of the equation you solve in the video is (2x/x-1 ) + (1/x-3)

Sir do you have a video about solving rational equations and inequalities?

[jakecarino]

Sir you have made a mistake at 3:07 when multiplying 2x(x-3)

[keethinnaidu]

Hi man can you tell me what grade this is you are teaching ?

[rockstar]

The thumbnail of the video is in subtraction, but the video is in addition.

[ramirorivera]

I still don't get it!!! I can factor out at the very beginning but after that I don't know how to multiply the factors to cancel it out! I just don't know!

[salwamohammed]

it helped me a lot but i wish that you can translate it with Arabic because it would be helpful for me

[ughhhh]

its a bit confusing. i don't really understand. also, do you film your lessons in front of a classroom full of people?

You are a beautiful beautiful man, god fucking bless you
