Q. The equation of a parabola is y=x2−10x+23. 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+23. To complete the square, we need to find the value that makes x2−10x a perfect square trinomial. We do this by taking half of the coefficient of x, which is −10, and squaring it. This gives us (−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.We add and subtract 25 to the equation, which gives us y=x2−10x+25+23−25. This allows us to form a perfect square trinomial without changing the value of the equation.
Rewrite and Simplify: Rewrite the equation with the perfect square trinomial and simplify.Now we have y=(x2−10x+25)+23−25. The expression in the parentheses is a perfect square trinomial, which can be factored as (x−5)2. Simplifying the constants gives us y=(x−5)2−2.
