Q. Put the quadratic into vertex form and state the coordinates of the vertex.y=x2+4x+29Vertex Form: y=Vertex: (□,□)
Identify vertex form: Identify the vertex form of a parabola.The vertex form of a parabola is y=a(x−h)2+k, where (h,k) is the vertex of the parabola.
Complete the square:Complete the square to rewrite the quadratic equation in vertex form.Given equation: y=x2+4x+29We need to find a value to add and subtract to complete the square.The coefficient of x is 4, so we take half of it, which is 2, and then square it to get 4.We add and subtract 4 inside the parentheses to complete the square.
Rewrite equation: Rewrite the equation by completing the square.y=x2+4x+4−4+29y=(x2+4x+4)−4+29y=(x+2)2+25Now the equation is in vertex form.
Identify vertex: Identify the vertex of the parabola. The vertex form of the equation is y=(x+2)2+25. Comparing this with the standard vertex form y=a(x−h)2+k, we find that h=−2 and k=25. Therefore, the vertex of the parabola is (−2,25).
