Web6 Oct 2024 · Eliminate the square root by squaring both sides of the equation as follows: (√x)2 = (3)2 x = 9 As a check, we can see that √9 = 3 as expected. Because the converse of the squaring property of equality is not necessarily true, solutions to the squared equation may not be solutions to the original. WebExample 1: Radical Equation With No Solution Consider the radical equation √ (x2 +2x) = x + 1 Since the radical (a square root) has an index of 2, the approach for solving is to square both sides (raise both sides to the power of 2): √ (x2 +2x) = x + 1 (√ (x2 +2x))2 = (x + 1)2 [square both sides] x2 + 2x = x2 + 2x + 1 [FOIL the right side]

WebSo yes, you are correct that a radical equation with the square root of an unknown equal to a negative number will produce no solution. This also applies to radicals with other even indices, like 4th roots, 6th roots, etc. However, radicals with odd indices (like a cube root) can produce solutions when equal to a negative.
