the imaginary part has the i attached to it, which is 4
4i is the imaginary part

Answer:
x+-16
Step-by-step explanation:
Hello there,
Well we are given with 3(x + 4)² and we need to simplify this expression...
- write out the expression: 3(x + 4)(x + 4)
- then we distribute the parentese: 3(x² +4x +4x +16)
- combine like terms: 3(x² + 8x + 16)
- distribute the 3 in the parentese: 3x² + 24x + 48
So another way to express this would be 3x² + 24x + 48.
Hope I helped,
Amna
