7–14. Find the derivative the following ways:
a. Using the Product Rule (Exercises 7–10) or the Quotient Rule (Exercises 11–14). Simplify your result.
y = x² - 2ax +a² / x-a, where a is a constant

Step 1: Identify the function as a quotient of two functions, where the numerator is \( u(x) = x^2 - 2ax + a^2 \) and the denominator is \( v(x) = x - a \).
Step 2: Recall the Quotient Rule for derivatives, which states that if \( y = \frac{u(x)}{v(x)} \), then \( y' = \frac{u'(x)v(x) - u(x)v'(x)}{(v(x))^2} \).
Step 3: Compute the derivative of the numerator, \( u'(x) = \frac{d}{dx}(x^2 - 2ax + a^2) = 2x - 2a \).
Step 4: Compute the derivative of the denominator, \( v'(x) = \frac{d}{dx}(x - a) = 1 \).
Step 5: Substitute \( u(x) \), \( u'(x) \), \( v(x) \), and \( v'(x) \) into the Quotient Rule formula and simplify the expression.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Product Rule

The Product Rule is a formula used to find the derivative of the product of two functions. If u(x) and v(x) are two differentiable functions, the derivative of their product is given by (u*v)' = u'v + uv'. This rule is essential when dealing with expressions where two functions are multiplied together, allowing for the correct application of differentiation.

Quotient Rule

The Quotient Rule is used to differentiate a function that is the quotient of two other functions. If u(x) and v(x) are differentiable functions, the derivative of their quotient is given by (u/v)' = (u'v - uv') / v². This rule is particularly important when the function is expressed as a fraction, ensuring that the differentiation accounts for both the numerator and denominator.

Simplification of Derivatives

Simplification of derivatives involves reducing the expression obtained after differentiation to its simplest form. This may include factoring, canceling common terms, or combining like terms. Simplifying the derivative is crucial for clarity and ease of interpretation, especially when analyzing the behavior of the function or finding critical points.
