WebExample 1: Vertex form Graph the equation. y=-2 (x+5)^2+4 y = −2(x + 5)2 + 4 This equation is in vertex form. y=\goldD {a} (x-\blueD h)^2+\greenD k y = a(x − h)2 + k This form reveals the vertex, (\blueD h,\greenD k) (h,k), which in our case is (-5,4) (−5,4). It also reveals whether the parabola opens up or down. WebTo solve a quadratic equation it must equal 0. Example: x2 = 5 x2−2x+1 = 0 2x2+3x−2 = 0 x 2 = 5 x 2 − 2 x + 1 = 0 2 x 2 + 3 x − 2 = 0. A quadratic equation can have zero, one or …
