Question
Find the roots
n1=−2,n2=2
Alternative Form
n1≈−1.414214,n2≈1.414214
Evaluate
n2−2
To find the roots of the expression,set the expression equal to 0
n2−2=0
Move the constant to the right-hand side and change its sign
n2=0+2
Removing 0 doesn't change the value,so remove it from the expression
n2=2
Take the root of both sides of the equation and remember to use both positive and negative roots
n=±2
Separate the equation into 2 possible cases
n=2n=−2
Solution
n1=−2,n2=2
Alternative Form
n1≈−1.414214,n2≈1.414214
