Q. Put the quadratic into vertex form and state the coordinates of the vertex.y=x2−12x+32Vertex Form: y=Vertex: (□,□)
Identify Vertex Form: Identify the vertex form of a parabola.The vertex form of a parabola is y=a(x−h)2+k, where (h,k) is the vertex of the parabola.
Complete the Square:Complete the square to rewrite the quadratic equation in vertex form.Given equation: y=x2−12x+32To complete the square, we need to find the value that makes x2−12x a perfect square trinomial.We take half of the coefficient of x, which is −12/2=−6, and square it to get 36.
Add and Subtract: Add and subtract the square of half the coefficient of x inside the equation.y=x2−12x+36−36+32We added and subtracted 36 to complete the square while keeping the equation balanced.
Rewrite Equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants.y=(x2−12x+36)−4y=(x−6)2−4Now the equation is in vertex form.
Identify Vertex: Identify the vertex of the parabola.The vertex form of the equation is y=(x−6)2−4.Comparing this with the standard vertex form y=a(x−h)2+k, we find that h=6 and k=−4.Therefore, the vertex of the parabola is (6,−4).
