Solving Quadratic Equations by Extracting Square Roots

In this video solving quadratic equations by completing the square will be discussed using three properties: If k greater than 0, then x^2 = k has no real solutions or roots: x= ±√𝒌 If k= 0, then x^2 = k has one real solution or root: x = 0. If k less than 0, then x^2 = k has no real solutions or roots.
