Q. The equation of a parabola is y=x2+2x−8. 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, which is y=a(x−h)2+k.
Start with given equation: Start with the given equation y=x2+2x−8.
Complete the square:Complete the square by adding and subtracting (22)2, which is 1, to the equation.y=x2+2x+1−1−8
Rewrite equation: Rewrite the equation grouping the perfect square trinomial and combining the constants.y=(x2+2x+1)−1−8y=(x+1)2−9
