If it is to match 3+1 which is 4 the value to satisfy X is -1

</em></h2><h2 /><h2><em>Explanation:
</em></h2><h2><em>Note that in general:
</em></h2><h2 /><h2><em>(

</em></h2><h2 /><h2><em>So we want to find a pair of factors a and b of 16 which differ by 6

⋅

</em></h2><h2 /><h2><em>Hence:
</em></h2><h2><em>
