Question 249782
On a problem like x^2 + 16 = 0 How do you find all the zeros?
:
A problems like this has no real roots, so it has no zeros
x^2 + 16 = 0
x^2 = -16
x = +/-{{{sqrt(-16)}}} square root of a neg not real
but can be written
x = +/- 4i
:
You can graph this and see y never = 0
{{{ graph( 300, 200, -6, 5, -10, 50, x^2+16) }}}
