Square Root Property

The Square Root Property states that if $$x^2 = a$$ , then $$x = \text{±}\sqrt{a}$$ , where a is a non-negative number.

Using the Square Root Property, the solutions are $$x = \text{±}6$$ .

Subtract 3 from both sides to isolate the term with r: $$9r^2 = 9$$ .

Divide both sides by 9 to get $$r^2 = 1$$ .

The solutions are $$r = \text{±}1$$ .

It allows for finding solutions by taking the square root of both sides of an equation.

The solution is $$x = 0$$ .

It means that the value under the square root is negative, indicating no real number satisfies the equation.

Substitute the solutions back into the original equation to verify they satisfy it.

The solution set is $$x = \text{±}5$$ .
