Answer:
The determinant is 15.
Step-by-step explanation:
You need to calculate the determinant of the given matrix.
1. Subtract column 3 multiplied by 3 from column 1 (C1=C1−(3)C3):
2. Subtract column 3 multiplied by 3 from column 2 (C2=C2−(3)C3):
3. Expand along the row 2: (See attached picture).
We get that the answer is 15. The determinant is 15.
For this case we have the following expression:
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:
