Q. Put the quadratic into vertex form and state the coordinates of the vertex.y=x2+2x+37Vertex Form: y=Vertex:Submit Answer
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 rewrite the quadratic equationy=x2+2x+37 in vertex form.First, we need to focus on the x-terms. We have x2+2x. To complete the square, we take half of the coefficient of x, which is 22=1, and square it, giving us 12=1. We will add and subtract this value inside the parentheses to maintain equality.
Rewrite Equation: Rewrite the equation by adding and subtracting the squared term.y=x2+2x+1−1+37Now, group the perfect square trinomial and the constants.y=(x2+2x+1)+36
Factor Trinomial: Factor the perfect square trinomial.The expression x2+2x+1factors to (x+1)2.So, the equation now reads y=(x+1)2+36.
Write in Vertex Form: Write the equation in vertex form and identify the vertex.The equation in vertex form is y=(x+1)2+36.The vertex of the parabola, given by the form y=a(x−h)2+k, is (h,k). In our equation, h=−1 and k=36.Therefore, the vertex is (−1,36).
