In this video, we will be discussing methods of manipulating equations to solve limits. The methods of manipulation discussed in this video are:
1. Factoring
Factor the function in order to simplify it, then try plugging in x=a again. Here are some common factoring rules in case you forgot! I haven’t made a video on this, but if I do I will link it here.
2. Conjugates
Multiply f(x) by its conjugate equation in order to simplify, then plug in x=a again.
Try these problems below for more practice:
(Hint: Multiply by the conjugate, but the sign you need to flip is NOT the one under the square root)
