Answer:
55 +48i
Step-by-step explanation:
Complex numbers can be treated as though they were binomials with a variable "i". At the end, any instance of i² can be replaced by -1.
(8 +3i)² = 8² + 2(8)(3i) +(3i)² = 64 +48i -9
= 55 +48i

Step-by-step explanation:
Inequalities of the type | x | > a always have solutions of the form
x < - a or x > a, thus
2x + 1 < - 5 OR 2x + 1 > 5 ( subtract 1 from both sides of both inequalities
2x < - 6 OR 2x > 4 ( divide both sides of both inequalities by 2 )
x < - 3 OR x > 2
