The equation of a parabola is y = x^2 + 10x + 20. 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 y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.Complete the Square: Complete the square to transform the given equation into vertex form. We start with the given equation y = x^2 + 10x + 20. To complete the square, we need to find the value that makes x^2 + 10x a perfect square trinomial. This value is (10/2)^2 = 25. We will add and subtract 25 inside the equation.Add and Subtract: Add and subtract 25 to the equation. y = x^2 + 10x + 25 - 25 + 20 Now, we have added 25 and subtracted 25, which keeps the equation balanced.Rewrite Equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants. y = (x^2 + 10x + 25) - 25 + 20 y = (x + 5)^2 - 5 We have now written the equation in vertex form, where (x + 5)^2 is the perfect square trinomial and -5 is the result of combining the constants.

Identify Vertex Form: Identify the vertex form of a parabola. The vertex form of a parabola is given by $y = a(x - h)^2 + k$ , where $(h, k)$ is the vertex of the parabola.
Complete the Square: Complete the square to transform the given equation into vertex form. $\newline$ We start with the given equation $y = x^2 + 10x + 20$ . To complete the square, we need to find the value that makes $x^2 + 10x$ a perfect square trinomial. This value is $(10/2)^2 = 25$ . We will add and subtract $25$ inside the equation.
Add and Subtract: Add and subtract $25$ to the equation. $\newline$ $y = x^2 + 10x + 25 - 25 + 20$ $\newline$ Now, we have added $25$ and subtracted $25$ , which keeps the equation balanced.
Rewrite Equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants. $\newline$ $y = (x^2 + 10x + 25) - 25 + 20$ $\newline$ $y = (x + 5)^2 - 5$ $\newline$ We have now written the equation in vertex form, where $(x + 5)^2$ is the perfect square trinomial and $-5$ is the result of combining the constants.
