Aug 3, 2016

$100$

#### Explanation:

This is all one term, but within thesquare bracket there are two terms which need to be simplified separately.

$2 \left[{\textcolor{red}{\left(9 - 8\right)}}^{2} + {\left(\textcolor{b l u e}{12 - 5}\right)}^{2}\right]$

=$2 \left[\textcolor{red}{{\left(1\right)}^{2}} + \textcolor{b l u e}{{\left(7\right)}^{2}}\right]$

=$2 \left[\textcolor{red}{1} + \textcolor{b l u e}{49}\right]$

=$2 \times 50$

=$100$
