Q. Which equation has the same solution as x219x8=2 x^{2}-19 x-8=2 ?\newline(x9.5)2=80.25 (x-9.5)^{2}=-80.25 \newline(x+9.5)2=100.25 (x+9.5)^{2}=100.25 \newline(x+9.5)2=80.25 (x+9.5)^{2}=-80.25 \newline(x9.5)2=100.25 (x-9.5)^{2}=100.25
  1. Simplify Equation: Simplify the given equation by moving all terms to one side to set the equation equal to zero.\newlinex219x82=0x^2 - 19x - 8 - 2 = 0\newlinex219x10=0x^2 - 19x - 10 = 0
  2. Find Vertex Form: Find the vertex form of the quadratic equation. The vertex form is given by (xh)2=k(x - h)^2 = k, where (h,k)(h, k) is the vertex of the parabola.\newlineTo find hh, use the formula h=b/(2a)h = -b/(2a), where aa is the coefficient of x2x^2 and bb is the coefficient of xx.\newlineIn this case, a=1a = 1 and b=19b = -19, so (h,k)(h, k)00.
  3. Calculate Vertex Coordinates: Calculate the value of kk by substituting hh back into the original equation.\newlinek=(9.5)219(9.5)10k = (9.5)^2 - 19(9.5) - 10\newlinek=90.25180.510k = 90.25 - 180.5 - 10\newlinek=90.2510k = -90.25 - 10\newlinek=100.25k = -100.25
  4. Write Vertex Form Equation: Write the equation in vertex form using the values of hh and kk.(x9.5)2=100.25 (x - 9.5)^2 = -100.25
  5. Compare with Choices: Compare the vertex form equation with the given choices to find the one that matches.\newlineThe correct choice is (x9.5)2=100.25(x - 9.5)^2 = -100.25, which is not listed among the choices provided. However, if we add 100.25100.25 to both sides of the equation, we get:\newline(x9.5)2+100.25=0(x - 9.5)^2 + 100.25 = 0\newline(x9.5)2=100.25(x - 9.5)^2 = -100.25
  6. Correct Mistake: Realize that there has been a mistake in the previous step. The correct step should be to add 100.25100.25 to both sides of the equation to get:\newline(x9.5)2=100.25(x - 9.5)^2 = 100.25\newlineThis matches one of the given choices.
