Question
Find the roots
x1=−24360−24360i,x2=24360+24360i
Alternative Form
x1≈−2.177939−2.177939i,x2≈2.177939+2.177939i
Evaluate
90+x4
To find the roots of the expression,set the expression equal to 0
90+x4=0
Move the constant to the right-hand side and change its sign
x4=0−90
Removing 0 doesn't change the value,so remove it from the expression
x4=−90
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±4−90

x=±(24360+24360i)
Separate the equation into 2 possible cases
x=24360+24360ix=−24360−24360i
Solution
x1=−24360−24360i,x2=24360+24360i
Alternative Form
x1≈−2.177939−2.177939i,x2≈2.177939+2.177939i
