Q. Put the quadratic into vertex form and state the coordinates of the vertex.y=x2+10x+24Vertex 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+10x+24To complete the square, we need to find a number that, when added and subtracted to the equation, forms a perfect square trinomial with x2+10x.Half of the linear coefficient (10) is 5, and squaring it gives us 25.So, we add and subtract 25 inside the equation to complete the square.y=x2+10x+25−25+24
Rewrite equation and combine: Rewrite the equation with the perfect square trinomial and combine the constants.y=(x2+10x+25)−1Now, factor the perfect square trinomial.y=(x+5)2−1This is the vertex form of the equation.
Identify vertex: Identify the vertex of the parabola.From the vertex form y=(x+5)2−1, we can see that the vertex (h,k) is (−5,−1).
