Q. Solve for x. Enter the solutions from least to greatest.3x2−33x+54=0lesser x=greater x=
Identify the quadratic equation: Identify the quadratic equation and its coefficients.The quadratic equation is 3x2−33x+54=0, where the coefficients are A=3, B=−33, and C=54.
Factor the quadratic equation: Factor the quadratic equation.We need to find two numbers that multiply to A⋅C(3⋅54) and add up to B(−33).The numbers that satisfy these conditions are −9 and −24 because −9⋅−24=216 and −9+−24=−33.
Rewrite the quadratic equation: Rewrite the quadratic equation using the numbers found in Step 2.3x2−9x−24x+54=0Group the terms: (3x2−9x)−(24x−54)=0
Factor by grouping: Factor by grouping.Factor out the common terms from each group:3x(x−3)−18(x−3)=0Now factor out the common binomial factor (x−3):(3x−18)(x−3)=0
Simplify the factored equation: Simplify the factored equation.Divide the first term by 3 to simplify:(x−6)(x−3)=0
Solve for x: Solve for x by setting each factor equal to zero.x−6=0 or x−3=0Solve each equation:x=6 or x=3
