Square Root Limits & Conjugates Made Easy

In this video, we learn how to solve square root limits using the conjugate method. Previously, we solved 0/0 limits by factoring. But sometimes factoring is not enough, especially when the limit contains a square root. That is where the conjugate trick helps. Topics covered: Square root limits What a conjugate is How to find the conjugate Why we change the sign How conjugates remove square roots Solving 0/0 indeterminate forms Conjugate in the numerator Conjugate in the denominator Common mistakes with conjugates Main idea: If direct substitution gives 0/0 and the expression has a square root, multiply by the conjugate.
