Gage Waters · Answer 1

Given with the function of x which is f (x) = 15x² + 360, we are tasked to solve for the value of x. The solution was discussed and shown below:

Set x=0, then we have:

0=15x² + 360

Transpose 360

15x² = - 360

Divide by 15

x² = - 360/15

x² = - 24

x = sqrt 4*6i

Therefore, the answer is letter B.
