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}.
