What is the product?

victus00 [196]

Answer:

$\begin{bmatrix}-2\\0 \end{bmatrix}$

Step-by-step explanation:

We have the product, $2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

It is known that,

'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.

So, we get,

$2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

⇒ $\begin{bmatrix}-1\times 2\\0\times 2 \end{bmatrix}$

⇒ $\begin{bmatrix}-2\\0 \end{bmatrix}$

So, the resulting product is $\begin{bmatrix}-2\\0 \end{bmatrix}$ .
