Multiply by the conjugate to simplify a radical rational expression

👉 Learn how to divide rational expressions having square root binomials. To divide a rational expression having a binomial denominator with a square root radical in one of the terms of the denominator, we multiply both the numerator and the denominator by the conjugate of the denominator and then simplify. When the square root in the denominator is covering both terms of the denominator, we multiply both the numerator and the denominator with the denominator and simplify.

Thanks so much for the help. I learned a lots from you in the order to teach my son . I am 51 years old and still learning . Keep the good work.

Hey bro; thanks for posting this video. My 10th grader was really struggling with math homework tonight and I couldn't remember the finer points for dealing with conjugates, but this video gave me exactly what I needed to help him understand what he was doing. I appreciate you.

man i was looking up guides in my native language(in which we learn math) and didn't get anywhere but the first video i watched in english was this and i got it immediately 😭thank you so much

Thank you for being a good teacher and explaining the thing my UMSL trig teacher was going to just look at me stupid for not knowing already..

Thank you for this video this helped me so much !!

The fact that my little brother is trying to learn this while he is younger than the video is genuinely surprising

Quick question im taking trig and im a little rusty on algebra when rationalizing a fraction with a square root do we multiply by the conjugate meaning same denominator but changing the sign so if that's the way to rationalize the denominator how come we change the sign why not just leave the sign alone
