Q. The equation of a parabola is y=x2−10x+27. Write the equation in vertex form.Write any numbers as integers or simplified proper or improper fractions.______
Identify Vertex Form: Identify the vertex form of a parabola.The vertex form of a parabola is given by the equation y=a(x−h)2+k, where (h,k) is the vertex of the parabola.
Complete the Square:Complete the square to rewrite the given equation in vertex form.We start with the given equation y=x2−10x+27. To complete the square, we need to find the value that makes x2−10x a perfect square trinomial. This value is given by (b/2)2, where b is the coefficient of x. In this case, b=−10, so (b/2)2=(−10/2)2=(−5)2=25. We will add and subtract this value inside the equation.
Add and Subtract Value: Add and subtract the value found in Step 2 to the equation.y=x2−10x+25+27−25This allows us to write the equation as a perfect square trinomial plus a constant.
Factor and Simplify: Factor the perfect square trinomial and simplify the constants.y=(x2−10x+25)+27−25y=(x−5)2+2Now the equation is in vertex form, where (h,k)=(5,2).
