Question
Find the roots
n1=−5,n2=5
Alternative Form
n1≈−2.236068,n2≈2.236068
Evaluate
n2−5
To find the roots of the expression,set the expression equal to 0
n2−5=0
Move the constant to the right-hand side and change its sign
n2=0+5
Removing 0 doesn't change the value,so remove it from the expression
n2=5
Take the root of both sides of the equation and remember to use both positive and negative roots
n=±5
Separate the equation into 2 possible cases
n=5n=−5
Solution
n1=−5,n2=5
Alternative Form
n1≈−2.236068,n2≈2.236068
