Learn how to use u substitution to integrate a polynomial

The video tutorial explains the process of finding U and DU for integration, addressing a problem with the initial setup, and solving it by dividing by 4. It then demonstrates the integration process, including handling constants, and concludes with the final steps to reach the solution.

What is the initial expression for U in the substitution method?

• X squared + 5

• X to the 3rd + 2

• X to the 5th + 1

• X to the 4th + 3

Why was the initial substitution attempt problematic?

• The variable was not defined

• The expressions were not equal

• The derivative was incorrect

• The constant was missing

What adjustment is made to the substitution to make it valid?

• Add a constant

• Divide by 4

• Subtract a constant

• Multiply by 4

What is the role of the constant factor during integration?

• It is factored out

• It is added to the integral

• It is multiplied by the integral

• It is ignored

What is the final step after integrating with substitution?

• Add a new variable

• Differentiate the result

• Substitute back the original expression

• Multiply by the constant
