Q. Which equation has the same solution as x2+11x+16=2 x^{2}+11 x+16=2 ?\newline(x+5.5)2=44.25 (x+5.5)^{2}=-44.25 \newline(x5.5)2=44.25 (x-5.5)^{2}=-44.25 \newline(x5.5)2=16.25 (x-5.5)^{2}=16.25 \newline(x+5.5)2=16.25 (x+5.5)^{2}=16.25
  1. Simplify Equation: Simplify the given equation by moving all terms to one side to set the equation to zero.\newlinex2+11x+162=0x^2 + 11x + 16 - 2 = 0\newlinex2+11x+14=0x^2 + 11x + 14 = 0
  2. Factor Quadratic: Factor the quadratic equation if possible.\newline(x+7)(x+2)=0(x + 7)(x + 2) = 0
  3. Solve for x: Solve for x by setting each factor equal to zero.\newlinex+7=0x + 7 = 0 or x+2=0x + 2 = 0\newlinex=7x = -7 or x=2x = -2
  4. Check Solutions: Check the given choices to see which one has the same solutions as the factored equation.\newlineWe are looking for an equation that has solutions x=7x = -7 and x=2x = -2.
  5. Analyze Choice 11: Analyze the first choice.\newline(x+5.5)2=44.25(x + 5.5)^2 = -44.25\newlineThis equation cannot have real solutions because the square of a real number cannot be negative.
  6. Analyze Choice 22: Analyze the second choice.\newline(x5.5)2=44.25(x - 5.5)^2 = -44.25\newlineThis equation also cannot have real solutions for the same reason as the first choice.
  7. Analyze Choice 33: Analyze the third choice.\newline(x5.5)2=16.25(x - 5.5)^2 = 16.25\newlineTaking the square root of both sides gives us two possible solutions:\newlinex5.5=±4.025x - 5.5 = \pm4.025\newlinex=5.5±4.025x = 5.5 \pm 4.025\newlinex=9.525x = 9.525 or x=1.475x = 1.475\newlineThese are not the solutions we are looking for.
  8. Analyze Choice 44: Analyze the fourth choice.\newline(x+5.5)2=16.25(x + 5.5)^2 = 16.25\newlineTaking the square root of both sides gives us two possible solutions:\newlinex+5.5=±4.025x + 5.5 = \pm4.025\newlinex=5.5±4.025x = -5.5 \pm 4.025\newlinex=1.475x = -1.475 or x=9.525x = -9.525\newlineThese are not the solutions we are looking for.
  9. No Matching Solutions: None of the given choices have the same solutions as the original equation x2+11x+14=0x^2 + 11x + 14 = 0.
