WebCompleting the square is a process that helps us rewrite a quadratic that's in the form ax 2 + bx + c into the form a(x - h) 2 +k. So, why would we want to do this? Well, for starters, if you want to graph the parabola, a(x - h) 2 +k is a form that's easier to work with because you automatically know that the vertex is at (h, k). (Also, if you're taking calculus, then … WebThe (real) solutions of a quadratic equation are the real numbers x which satisfy the equation or make the statement true. There are three possible scenarios 1.There is exactly one real solution. 2.There are two distinct (not the same) real solutions. 3.There are no real solutions (in this case there are two solutions in the complex numbers).

WebSolve by completing the square. x^ {2}+16x+17=-47. Take a closer look at this problem and you may see something familiar. Instead of completing the square, try adding 47 to both sides in the equation. The equation x^ {2}+16x+17=−47 becomes x^ {2}+16x+64=0.
