Find the Derivative - d/dx -xe^x

Problem

(d(−)*x*ex)/d(x)

Solution

1. Identify the rule needed for differentiation. Since the expression is a product of two functions, −x and ex the product rule must be applied.

2. Apply the product rule, which states that (d(u)*v)/d(x)=ud(v)/d(x)+vd(u)/d(x) Let u=−x and v=ex

3. Differentiate the individual components. The derivative of −x is −1 and the derivative of ex is ex

4. Substitute these derivatives into the product rule formula.

(d(−)*x*ex)/d(x)=−xd(ex)/d(x)+ex(d(−)*x)/d(x)

5. Simplify the resulting expression by performing the differentiation and combining terms.

(d(−)*x*ex)/d(x)=−x*ex+ex*(−1)

6. Factor out the common term ex to reach the final simplified form.

(d(−)*x*ex)/d(x)=−x*ex−ex

Final Answer

(d(−)*x*ex)/d(x)=−ex*(x+1)
