multiply. write the answer in standard form.

2i (7 - i) = \square

Using the distributive property (a(b - c) = ab - ac), we have $2i(7 - i)=2i\times7 - 2i\times i$.

Recall that $i^2=- 1$. So, $2i\times7 = 14i$ and $2i\times i=2i^{2}=2\times(-1)=-2$. Then the expression becomes $14i-(-2)=2 + 14i$.

$2 + 14i$
