<span>The pair of integers that I chose are:
(a) sum is –3
5 + (-8) = -3
(b) difference is –5
2 - 7 = -5
(c) difference is 2
14 -12 = 2
(d) sum is 0
2 - 2 = 0</span>
The upside down u (intersection) just wants us to find what the two sets have in common....
which is 4 and 6
\left[x _{2}\right] = \left[ 2+\frac{\sqrt{6}}{2}\right][x2]=[2+2√6] this is answer
