Question
Find the roots
o1=−2,o2=2
Alternative Form
o1≈−1.414214,o2≈1.414214
Evaluate
o2−2
To find the roots of the expression,set the expression equal to 0
o2−2=0
Move the constant to the right-hand side and change its sign
o2=0+2
Removing 0 doesn't change the value,so remove it from the expression
o2=2
Take the root of both sides of the equation and remember to use both positive and negative roots
o=±2
Separate the equation into 2 possible cases
o=2o=−2
Solution
o1=−2,o2=2
Alternative Form
o1≈−1.414214,o2≈1.414214
