Question
Find the roots
r1=−10,r2=10
Alternative Form
r1≈−3.162278,r2≈3.162278
Evaluate
r2−10
To find the roots of the expression,set the expression equal to 0
r2−10=0
Move the constant to the right-hand side and change its sign
r2=0+10
Removing 0 doesn't change the value,so remove it from the expression
r2=10
Take the root of both sides of the equation and remember to use both positive and negative roots
r=±10
Separate the equation into 2 possible cases
r=10r=−10
Solution
r1=−10,r2=10
Alternative Form
r1≈−3.162278,r2≈3.162278
