Solve using the Square Root Property (r+6)^2=15

Math
(r+6)2=15
Take the square root of each side of the equation to set up the solution for r
(r+6)2⋅12=±15
Remove the perfect root factor r+6 under the radical to solve for r.
r+6=±15
The complete solution is the result of both the positive and negative portions of the solution.
Tap for more steps…
First, use the positive value of the ± to find the first solution.
r+6=15
Subtract 6 from both sides of the equation.
r=15-6
Next, use the negative value of the ± to find the second solution.
r+6=-15
Subtract 6 from both sides of the equation.
r=-15-6
The complete solution is the result of both the positive and negative portions of the solution.
r=15-6,-15-6
r=15-6,-15-6
The result can be shown in multiple forms.
Exact Form:
r=15-6,-15-6
Decimal Form:
r=-2.12701665…,-9.87298334…
