Q. Which equation has the same solution as x2+17x18=6 x^{2}+17 x-18=6 ?\newline(x+8.5)2=48.25 (x+8.5)^{2}=-48.25 \newline(x8.5)2=48.25 (x-8.5)^{2}=-48.25 \newline(x8.5)2=96.25 (x-8.5)^{2}=96.25 \newline(x+8.5)2=96.25 (x+8.5)^{2}=96.25
  1. Simplify the equation: First, let's simplify the given equation by moving all terms to one side to set the equation to zero.\newlinex2+17x186=0x^2 + 17x - 18 - 6 = 0\newlinex2+17x24=0x^2 + 17x - 24 = 0
  2. Complete the square: Now, we need to find an equation that has the same solutions as x2+17x24=0x^2 + 17x - 24 = 0. To do this, we can complete the square to transform the given quadratic equation into a form that matches one of the choices.\newlineFirst, we calculate the value needed to complete the square. We take half of the coefficient of xx, which is 172\frac{17}{2}, and square it.\newline(172)2=8.52=72.25(\frac{17}{2})^2 = 8.5^2 = 72.25
  3. Add and subtract value: Next, we add and subtract this value inside the equation to complete the square.\newlinex2+17x+72.2572.2524=0x^2 + 17x + 72.25 - 72.25 - 24 = 0\newlineNow, we group the perfect square trinomial and the constants.\newline(x+8.5)272.2524=0(x + 8.5)^2 - 72.25 - 24 = 0
  4. Group the terms: Combine the constants to simplify the equation further.\newline(x+8.5)296.25=0(x + 8.5)^2 - 96.25 = 0
  5. Combine the constants: Finally, we can rearrange the equation to match one of the choices.\newline(x+8.5)2=96.25(x + 8.5)^2 = 96.25\newlineThis equation has the same solution as the original equation x2+17x18=6x^2 + 17x - 18 = 6.
