Question
Find the roots
o1=−2i,o2=2i
Evaluate
4+o2
To find the roots of the expression,set the expression equal to 0
4+o2=0
Move the constant to the right-hand side and change its sign
o2=0−4
Removing 0 doesn't change the value,so remove it from the expression
o2=−4
Take the root of both sides of the equation and remember to use both positive and negative roots
o=±−4
