I’m not sure if this is how you’re supposed to write the summary statement, but I got the answer of (2x+3)(x-1)(-2/(x-2)) (see photo to see my work
Answer:
2x²+ x - 3 +
Step-by-step explanation:
We have to divide the polynomial (2x³- 3x²- 5x + 4) by (x - 2) using synthetic division.
2 | 2 -3 -5 4
× 4 2 -6
-------------------------
2 1 -3 -2
Now we will form the expression in the form of fraction again
2x²+ 1.(x) - 3 +
Therefore, 2x²+ x - 3 + will be the answer.

Answer with Step-by-step explanation:
We are given that
A and B are matrix.
A.We know that for two square matrix A and B
Then,
Therefore, it is true.
B. det A is the product of diagonal entries in A.
It is not true for all matrix.It is true for upper triangular matrix.
Hence, it is false.
C.
When is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.
Hence, it is false.
D.An elementary row operation on A does not change the determinant.
It is true because when an elementary operation applied then the value of matrix A does not change.
