Use a Conjugate to Rationalize the Denominator | Algebra | HS.N-RN.A.2 🖤

In this YouTube Shorts math video, we quickly show how to simplify a radical expression and write it in simplest form. We will review why simplifying requires rationalizing the denominator using the conjugate to create a difference of squares. You’ll see how multiplying the numerator and denominator by the conjugate is the same as multiplying by 1, which keeps the expression equivalent. We then use the difference of squares to simplify the denominator and finish by identifying and canceling like factors in the numerator and denominator. Fast, clear, and perfect for a quick refresher on radical simplification!
