Rationalizing the denominator with a radical

👉 Lean how to divide rational expressions with a radical in the denominator. To divide rational expressions with a radical in the denominator, we rationalize the denominator by multiplying both the numerator and denominator by the denominator. If the denominator is a binomial then we will multiply both the numerator and the denominator by the conjugate of the denominator to create a difference of two squares in the denominator.

It's been 14 years since I've done math. I started college algebra this week, and these videos have helped me so much. These videos might be 10 years old, but they have been wonderful in helping me bring back an age old subject long forgotten. Thank you!

I have been looking online for an hour on how to solve this equation and you just taught me how in 3 minutes, great video

I am from Iraq and I watch this video you help me in this lesson because I was dont understand this lesson so thank you so match

[olivemd]

Great explanation. Clear and to the point. Thank you.

Thanks. That's exactly what I was looking for (why the product of two roots is a whole number).

On This 0:29 You say we can't write it as a fraction...I think we can write it as a fraction as root 3 upon 1... yes or no

[dudedude]

Oh... So we are able to rationalize a fraction if it simply has a square root but if it has 1 minus square root we would have to use a conjugant plz correct me if i am mistaken

tbh I'm still listening to trippie redd n juice while I'm taking notes #rip 8th pd

Now I’m confused... my teachers example has square root of 2 equal to square root of 4

[lolaadeniyi]

I feel like the way you did it was a bit more complicated than my math teacher does it.😖😨😧😭😢
