WebJul 25, 2024 · Answer. Sometimes after squaring both sides of an equation, we still have a variable inside a radical. When that happens, we repeat Step 1 and Step 2 of our procedure. We isolate the radical and square both … WebThe square root operation gives us only the principal square root, or positive positive square root. For example, \sqrt {4}=2 4 = 2, not both -2 −2 and 2 2 even though (-2)^2=2^2=4 (−2)2 = 22 = 4. If a solution leads to equating the square root of a number to a negative number, then that solution is extraneous.
