Can you please help me with this problem because I am having a difficult time with it. Can you do it step by step and can you make the writing a little clearer so I can follow along and make easier for me to read 

### Linear Transformations - Educational Material

---

**Problem 1:**

Let \( T : P_2 \rightarrow P_3 \) be the linear transformation defined by 

\[ T \left( p(x) \right) = (x + 1)p(x) + p'(1) + \int_0^{3x} 2p(t) \, dt. \]

**Task:**

Find \([T]\), the matrix of \( T \) relative to the standard bases of \( P_2 \) (\(\{1, x, x^2\}\)) and \( P_3 \) (\(\{1, x, x^2, x^3\}\)).

---

In this problem, you are given a linear transformation \( T \) from the polynomial space \( P_2 \) to the polynomial space \( P_3 \). You are to find the matrix representation of this transformation relative to the standard bases provided for these polynomial spaces.

Here are the steps you need to follow to solve this problem:

1. Express a general polynomial in \( P_2 \) as \( p(x) = a + bx + cx^2 \), where \( a, b, \) and \( c \) are constants.
2. Apply the transformation \( T \) to this general polynomial \( p(x) \).
3. Express \( T(p(x)) \) in terms of the basis elements of \( P_3 \).
4. Derive the matrix representation \([T]\) by determining how the transformation affects each basis element of \( P_2 \) and expressing the result in terms of the basis elements of \( P_3 \).

By following these steps, you can systematically find the matrix representation of the given linear transformation \( T \).
