Q. Put the quadratic into vertex form and state the coordinates of the vertex.y=x2−10x+50Vertex 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=x2−10x+50To complete the square, we need to find a value that makes x2−10x a perfect square trinomial.The value to add and subtract is (210)2=52=25.
Add and Subtract Value: Add and subtract the value found in Step 2 inside the equation.y=x2−10x+25+50−25y=(x2−10x+25)+25Now, the equation x2−10x+25 is a perfect square trinomial.
Factor and Simplify: Factor the perfect square trinomial and simplify the equation.y=(x−5)2+25This is the equation in vertex form.
Identify Parabola Vertex: Identify the vertex of the parabola.The vertex form of the equation is y=(x−h)2+k.Comparing this with the equation from Step 4, we get h=5 and k=25.Therefore, the vertex of the parabola is (5,25).
