Identify the quadratic equation: Identify the quadratic equation to solve for x.The given equation is x2−12x+36=0.We need to find two numbers that multiply to 36 and add up to −12.
Find the two numbers: Find the two numbers that satisfy the conditions.The numbers −6 and −6 multiply to 36 and add up to −12.
Write the factored form: Write the factored form of the quadratic equation using the numbers found.The factored form is (x−6)(x−6)=0.
Set each factor equal to zero: Set each factor equal to zero and solve for x.\ First, set x−6=0 and solve for x.\ Adding 6 to both sides gives us x=6.
Find the unique solution: Since both factors are the same, we only have one unique solution.The solution is x=6.
