okay in this example we're going to integrate 4t squared plus 3 and then the whole thing here is being squared let's go ahead and try to work through it solution so to do this i think one way to do it is to simply expand it out and because there's a two here you can write it twice and just multiply it out or you can take a shortcut let's go ahead a...

Questions & Answers
Q: What are the two methods mentioned for expanding the squared polynomial function?
The two methods mentioned are multiplying it out or using the (a + b)^2 formula. While multiplying it out is longer, the (a + b)^2 formula provides a shortcut for expansion.
Q: How do you apply the power rule to find the integral of the polynomial function?
To apply the power rule, you drop the integral sign and increase the power of each term by 1. Then, divide each term by the new power. Finally, add any constant of integration (C) to the expression.
Q: Why is the constant of integration included in the final answer?
The constant of integration is included because when we integrate, we lose information about the original constant term. Including the constant of integration accounts for all possible values that the constant term could have had.
Q: Can the power rule be applied to any polynomial function?
Yes, the power rule can be applied to any polynomial function as long as the power is not 1. The power rule simplifies the process of integrating polynomial functions.
