Question
Find the roots
s1=−202,s2=202
Alternative Form
s1≈−14.21267,s2≈14.21267
Evaluate
s2−202
To find the roots of the expression,set the expression equal to 0
s2−202=0
Move the constant to the right-hand side and change its sign
s2=0+202
Removing 0 doesn't change the value,so remove it from the expression
s2=202
Take the root of both sides of the equation and remember to use both positive and negative roots
s=±202
Separate the equation into 2 possible cases
s=202s=−202
Solution
s1=−202,s2=202
Alternative Form
s1≈−14.21267,s2≈14.21267
