Can linear equations have square roots

Weband it gives us two complex roots (which are different) as the square root of a negative number is a complex number. Thus, the quadratic equation has two complex roots when b 2 - 4ac < 0. Note: A quadratic equation can never have one complex root. The complex roots always occur in pairs. i.e., if a + bi is a root then a - bi is also a root. 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 …
