Question
Find the roots
m1=−230,m2=230
Alternative Form
m1≈−10.954451,m2≈10.954451
Evaluate
m2−120
To find the roots of the expression,set the expression equal to 0
m2−120=0
Move the constant to the right-hand side and change its sign
m2=0+120
Removing 0 doesn't change the value,so remove it from the expression
m2=120
Take the root of both sides of the equation and remember to use both positive and negative roots
m=±120
Simplify the expression
