Question
Find the roots
x1=−11,x2=11
Alternative Form
x1≈−3.316625,x2≈3.316625
Evaluate
x2−11
To find the roots of the expression,set the expression equal to 0
x2−11=0
Move the constant to the right-hand side and change its sign
x2=0+11
Removing 0 doesn't change the value,so remove it from the expression
x2=11
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±11
Separate the equation into 2 possible cases
x=11x=−11
Solution
x1=−11,x2=11
Alternative Form
x1≈−3.316625,x2≈3.316625
