Question
Find the roots
M1=−7,M2=7
Alternative Form
M1≈−2.645751,M2≈2.645751
Evaluate
M2−7
To find the roots of the expression,set the expression equal to 0
M2−7=0
Move the constant to the right-hand side and change its sign
M2=0+7
Removing 0 doesn't change the value,so remove it from the expression
M2=7
Take the root of both sides of the equation and remember to use both positive and negative roots
M=±7
Separate the equation into 2 possible cases
M=7M=−7
Solution
M1=−7,M2=7
Alternative Form
M1≈−2.645751,M2≈2.645751
