Web3 Oct 2024 · Square Root Property x 2 = a if and only if x = ± a In other words, x 2 = a if and only if x = a or x = − a Example 11.1.1 Solve: x 2 = 81 Solution We could rewrite the equation so that 81 is on the left and then solve by factoring. However, for the sake of the property, we solve this equation by applying the square root property.
