Question

${2n}^{2} + 14 - 16$

Answer 1

Hopefully I am factoring...

1st take the 2 out of the expression
$2(n^2+7n-8)$

Look at the 2nd sign, since it is negative the signs in the factors will be +/-.  Now we need the numbers that multilpy to 8 and have a difference of 7, which will be 8 and 1.
$2(n+8)(n-1)$ - factored form
