Q. Solve for x. Enter the solutions from least to greatest.x2−12x+27=0 lesser x=□ greater x=□
Identify quadratic equation: Identify the quadratic equation to be solved.The given quadratic equation is x2−12x+27=0. We need to find two numbers that multiply to 27 and add up to −12.
Factor the equation: Factor the quadratic equation.The two numbers that multiply to 27 and add up to −12 are −9 and −3 because (−9)×(−3)=27 and (−9)+(−3)=−12. So, we can write the equation as (x−9)(x−3)=0.
Solve for x (first factor): Solve for x by setting each factor equal to zero.First, set the first factor equal to zero: x−9=0. Then, solve for x by adding 9 to both sides: x=9.
Solve for x (second factor): Solve for x using the second factor.Now, set the second factor equal to zero: x−3=0. Then, solve for x by adding 3 to both sides: x=3.
Write the solutions: Write the solutions in ascending order.The solutions are x=3 and x=9. Since 3 is less than 9, we write them as lesser x=3 and greater x=9.
