What is the limit of x^2-4/x-2 as x approaches 2?
Question
What is the limit of x^2-4/x-2 as x approaches 2?
Solution
The limit of the function (x^2 - 4) / (x - 2) as x approaches 2 can be found by factoring the numerator and simplifying the expression.
Step 1: Factor the numerator. The expression x^2 - 4 is a difference of squares, which can be factored into (x - 2)(x + 2).
So, the function becomes (x - 2)(x + 2) / (x - 2).
Step 2: Simplify the expression. The (x - 2) terms cancel out, leaving us with x + 2.
Step 3: Substitute x = 2 into the simplified expression. This gives us 2 + 2 = 4.
So, the limit of the function (x^2 - 4) / (x - 2) as x approaches 2 is 4.
