Q. Put the quadratic into vertex form and state the coordinates of the vertex.\newliney=x2+10x+9 y=x^{2}+10 x+9 \newlineVertex Form: y= y= \newlineVertex: (,) (\square, \square)
  1. Identify vertex form: Identify the vertex form of a parabola.\newlineThe vertex form of a parabola is given by y=a(xh)2+ky = a(x - h)^2 + k, where (h,k)(h, k) is the vertex of the parabola.
  2. Given quadratic equation: Consider the given quadratic equation y=x2+10x+9y = x^2 + 10x + 9.\newlineTo convert this into vertex form, we need to complete the square.
  3. Factor out coefficient: Factor out the coefficient of the x2x^2 term if it is not 11. In this case, the coefficient is already 11, so we can proceed to the next step.
  4. Find square of half: Find the square of half the coefficient of the xx term to complete the square.\newlineHalf of the coefficient of xx is 102=5\frac{10}{2} = 5.\newlineSquaring this gives us 52=255^2 = 25.
  5. Add and subtract square: Add and subtract the square of half the coefficient of xx inside the equation.\newliney=x2+10x+(52)(52)+9y = x^2 + 10x + (5^2) - (5^2) + 9\newlineThis step ensures that we can form a perfect square trinomial while keeping the equation balanced.
  6. Rewrite equation grouping: Rewrite the equation grouping the perfect square trinomial and combining the constants.\newliney=(x2+10x+25)25+9y = (x^2 + 10x + 25) - 25 + 9\newliney=(x+5)216y = (x + 5)^2 - 16
  7. Equation in vertex form: Now the equation is in vertex form.\newlineVertex Form: y=(x+5)216y = (x + 5)^2 - 16
  8. Identify vertex coordinates: Identify the coordinates of the vertex from the vertex form.\newlineThe vertex (h,k)(h, k) is given by the values inside the parenthesis and the constant term.\newlineHere, h=5h = -5 and k=16k = -16.\newlineVertex: (5,16)(-5, -16)
