Question: Find the limit of the following algebraic function algebraically:

limx2x24x+4x2\lim_{x \to 2} \frac{x^2 - 4x + 4}{x - 2}

Answer:

To find the limit of the given function as x approaches 2, we can first simplify the function by factoring the numerator:

limx2(x2)(x2)x2\lim_{x \to 2} \frac{(x - 2)(x - 2)}{x - 2}

Here, we can see that the term (x2)(x - 2) exists in both the numerator and denominator. We can cancel out this term:

limx2(x2)\lim_{x \to 2} (x - 2)

Now, as x approaches 2, we can simply plug in 2 for x:

limx2(x2)=22=0\lim_{x \to 2} (x - 2) = 2 - 2 = 0

Hence, the limit of the given function as x approaches 2 is 0.

Thus, the final answer is:

limx2x24x+4x2=0\boxed{\lim_{x \to 2} \frac{x^2 - 4x + 4}{x - 2} = 0}
