m2-49=0
Add 49 to both sides of the equation.
m2=49
Take the square root of both sides of the equation to eliminate the exponent on the left side.
m=±49
Simplify the right side of the equation.
Rewrite 49 as 72.
m=±72
Pull terms out from under the radical, assuming positive real numbers.
m=±7
m=±7
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
m=7
Next, use the negative value of the ± to find the second solution.
m=-7
The complete solution is the result of both the positive and negative portions of the solution.
m=7,-7
m=7,-7
m=7,-7
Solve using the Square Root Property m^2-49=0
