Final answer:
To simplify the given matrix expression, multiply the matrices and perform addition.
Step-by-step explanation:
To simplify the given matrix expression, we need to perform matrix operations.
Let's start with the multiplication:
- Multiply the matrix [4 -5] by each element of the matrix [-12 20; -8 10].
- Calculate the resulting matrix.
After that, we need to add the resulting matrix to the matrix [-4 -3; 2].
Simplifying the matrices will result in the final matrix expression.
