361=x2
Rewrite the equation as x2=361.
x2=361
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x=±361
Simplify the right side of the equation.
Rewrite 361 as 192.
x=±192
Pull terms out from under the radical, assuming positive real numbers.
x=±19
x=±19
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.
x=19
Next, use the negative value of the ± to find the second solution.
x=-19
The complete solution is the result of both the positive and negative portions of the solution.
x=19,-19
x=19,-19
x=19,-19
Solve using the Square Root Property 361=x^2
