Simplify the expression
m2−60
Evaluate
m2−0−0−60
Solution
m2−60
Show Solution
Find the roots
m1=−215,m2=215
Alternative Form
m1≈−7.745967,m2≈7.745967
Evaluate
m2−0−0−60
To find the roots of the expression,set the expression equal to 0
m2−0−0−60=0
Removing 0 doesn't change the value,so remove it from the expression
m2−0−60=0
Removing 0 doesn't change the value,so remove it from the expression
m2−60=0
Move the constant to the right-hand side and change its sign
m2=0+60
Removing 0 doesn't change the value,so remove it from the expression
m2=60
Take the root of both sides of the equation and remember to use both positive and negative roots
m=±60
