Q. Which equation has the same solution as x2+11x+16=2 ?(x+5.5)2=−44.25(x−5.5)2=−44.25(x−5.5)2=16.25(x+5.5)2=16.25
Simplify Equation: Simplify the given equation by moving all terms to one side to set the equation to zero.x2+11x+16−2=0x2+11x+14=0
Factor Quadratic: Factor the quadratic equation if possible.(x+7)(x+2)=0
Solve for x: Solve for x by setting each factor equal to zero.x+7=0 or x+2=0x=−7 or x=−2
Check Solutions: Check the given choices to see which one has the same solutions as the factored equation.We are looking for an equation that has solutions x=−7 and x=−2.
Analyze Choice 1: Analyze the first choice.(x+5.5)2=−44.25This equation cannot have real solutions because the square of a real number cannot be negative.
Analyze Choice 2: Analyze the second choice.(x−5.5)2=−44.25This equation also cannot have real solutions for the same reason as the first choice.
Analyze Choice 3: Analyze the third choice.(x−5.5)2=16.25Taking the square root of both sides gives us two possible solutions:x−5.5=±4.025x=5.5±4.025x=9.525 or x=1.475These are not the solutions we are looking for.
Analyze Choice 4: Analyze the fourth choice.(x+5.5)2=16.25Taking the square root of both sides gives us two possible solutions:x+5.5=±4.025x=−5.5±4.025x=−1.475 or x=−9.525These are not the solutions we are looking for.
No Matching Solutions: None of the given choices have the same solutions as the original equation x2+11x+14=0.
