Q. Solve for x. Enter the solutions from least to greatest.x2−11x+18=0 lesser x=□ greater x=□
Identify Equation Type: Identify the type of equation. We have a quadratic equation in the form x2−11x+18=0.
Factor Quadratic Equation: Factor the quadratic equation. Look for two numbers that multiply to 18 and add up to −11. The numbers are −9 and −2 because −9×−2=18 and −9+−2=−11. So, the factored form is (x−9)(x−2)=0.
Set Factors Equal: Set each factor equal to zero. If (x−9)(x−2)=0, then either x−9=0 or x−2=0.
Solve for x (1st equation): Solve for x in the first equation. Add 9 to both sides of x−9=0 to get x=9.
Solve for x (2nd equation): Solve for x in the second equation. Add 2 to both sides of x−2=0 to get x=2.
List Solutions: List the solutions from least to greatest. The lesser x is 2, and the greater x is 9.
