Solve Matrix

$$\left( \begin{array} { l l } { 3 } & { 3 } \\ { 3 } & { 2 } \end{array} \right)$$

Calculate Determinant

$$-3$$

Steps Using Diagonal Rule

Find the determinant of the matrix.

$$det(\left(\begin{matrix}3&3\\3&2\end{matrix}\right))$$

For the 2\times 2 matrix \left(\begin{matrix}a&b\\c&d\end{matrix}\right), the determinant is ad-bc.

$$3\times 2-3\times 3$$

Multiply 3 times 2.

$$6-3\times 3$$

Multiply 3 times 3.

$$6-9$$

Subtract 9 from 6.

$$-3$$

Evaluate

$$\left(\begin{matrix}3&3\\3&2\end{matrix}\right)$$
