Q. (x+1)2−36=0What are the solutions to the given equation?Choose 1 answer:(A) x=−5,x=7(B) x=−5,x=−7(C) x=5,x=−7(D) x=5,x=7
Set Equation to Zero: Set the equation equal to zero.(x+1)2−36=0This is a quadratic equation in the form of a difference of squares, which can be factored.
Factor the Equation: Factor the equation.(x+1)2−36=(x+1+6)(x+1−6)=0This is because a2−b2=(a+b)(a−b), where a=(x+1) and b=6.
Solve for x: Set each factor equal to zero and solve for x.(x+1+6)=0 or (x+1−6)=0x+7=0 or x−5=0
Final Solutions: Solve each equation for x.x+7=0 gives x=−7x−5=0 gives x=5
