Identify Common Factor: Step Title: Identify the Common FactorConcise Step Description: Identify the greatest common factor of the terms in the polynomial.Step Calculation: The greatest common factor of 20u3, 10u2, and 18u is 2u.Step Output: Greatest common factor: 2u
Factor Out Common Factor: Step Title: Factor Out the Greatest Common FactorConcise Step Description: Factor out the greatest common factor from each term in the polynomial.Step Calculation: Factoring out 2u from each term gives us 2u(10u2−5u+9).Step Output: Factored polynomial: 2u(10u2−5u+9)
Check Further Factoring: Step Title: Check for Further FactoringConcise Step Description: Check if the quadratic expression within the parentheses can be factored further.Step Calculation: The quadratic expression 10u2−5u+9 does not factor nicely since the discriminant (b2−4ac) is negative: (−5)2−4(10)(9)=25−360=−335.Step Output: The quadratic expression cannot be factored further.
Subtract 9: Step Title: Subtract 9 from Both SidesConcise Step Description: To solve the equation, subtract 9 from both sides to set the equation to zero.Step Calculation: 20u3−10u2+18u−9=0Step Output: Adjusted equation: 20u3−10u2+18u−9=0
Factor Out Common Factor Again: Step Title: Factor Out the Greatest Common Factor AgainConcise Step Description: Factor out the greatest common factor from the adjusted equation.Step Calculation: The greatest common factor of 20u3, 10u2, 18u, and 9 is 1, which does not change the equation.Step Output: Factored equation: 2u(10u2−5u+9)−9=0
Check Factoring or Solutions: Step Title: Check for Factoring or SolutionsConcise Step Description: Check if the adjusted equation can be factored or if there are any solutions.Step Calculation: The equation 2u(10u2−5u+9)−9=0 does not factor further, and there are no obvious solutions.Step Output: The equation cannot be factored further and has no simple solutions.
