Write a quadratic function in vertex form

Full solution

Q. The equation of a parabola is

y = x^2 - 10x + 16

. Write the equation in vertex form.

\newline

Write any numbers as integers or simplified proper or improper fractions.

\newline

______

Identify vertex form: Identify the vertex form of a parabola. $\newline$ 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. $\newline$ We have the equation $y = x^2 - 10x + 16$ . To complete the square, we need to find the value that makes $x^2 - 10x$ a perfect square trinomial. This value is given by $(\frac{10}{2})^2 = 25$ . We will add and subtract $25$ inside the equation.
Add and subtract: Add and subtract $25$ to the equation. $\newline$ $y = x^2 - 10x + 25 + 16 - 25$ $\newline$ Now, we have added $25$ and subtracted $25$ , which keeps the equation balanced.
Group and combine: Group the perfect square trinomial and combine the constants. $\newline$ $y = (x^2 - 10x + 25) + 16 - 25$ $\newline$ $y = (x - 5)^2 - 9$ $\newline$ Now, we have the equation in vertex form, where $(x - 5)^2$ is the perfect square trinomial and $-9$ is the combination of the constants.
