Q. The equation of a parabola is y=x2+8x+17. 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 Square Transformation:Complete the square to transform the given equation into vertex form.The given equation is y=x2+8x+17. To complete the square, we need to find the value that makes x2+8x a perfect square trinomial. This value is (28)2=42=16. We will add and subtract 16 inside the equation.
Add and Subtract 16: Add and subtract 16 to the equation.y=x2+8x+17y=x2+8x+16+17−16Now, we have added 16 and subtracted 16, which keeps the equation balanced.
Rewrite Equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants.y=(x2+8x+16)+17−16y=(x+4)2+1Now, the equation is in vertex form, where (x+4)2 is the perfect square trinomial and 1 is the combined constant.
