How do you do completing the square
WebThis is what is known as the vertex form of a quadratic equation: it is for finding the vertex (obviously). Given the expression (x+a)^2+b, the vertex of this quadratic is (-a,b). So, the b-value is the y-value of the vertex of the quadratic. For example: (x-7)^2 - 23 a = -7 and b = -23 So, the vertex of this quadratic is (- (-7),-23), or (7,-23). WebComplete the square formula. In mathematics, completing the square is used to compute quadratic polynomials. Completing the Square Formula is given as: ax 2 + bx + c ⇒ (x + p) 2 + constant. The quadratic formula is derived using a method of completing the square. Let’s see. Given a quadratic equation ax 2 + bx + c = 0;
