Question
Find the roots
x1=−2×i,x2=2×i
Alternative Form
x1≈−1.414214i,x2≈1.414214i
Evaluate
x2+2
To find the roots of the expression,set the expression equal to 0
x2+2=0
Move the constant to the right-hand side and change its sign
x2=0−2
Removing 0 doesn't change the value,so remove it from the expression
x2=−2
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±−2
Simplify the expression
