Full solution

Q. Factor completely,\newline20u310u2+18u=920u^{3}-10u^{2}+18u=9
  1. Identify Common Factor: Step Title: Identify the Common Factor\newlineConcise Step Description: Identify the greatest common factor of the terms in the polynomial.\newlineStep Calculation: The greatest common factor of 20u320u^3, 10u210u^2, and 18u18u is 2u2u.\newlineStep Output: Greatest common factor: 2u2u
  2. Factor Out Common Factor: Step Title: Factor Out the Greatest Common Factor\newlineConcise Step Description: Factor out the greatest common factor from each term in the polynomial.\newlineStep Calculation: Factoring out 2u2u from each term gives us 2u(10u25u+9)2u(10u^2 - 5u + 9).\newlineStep Output: Factored polynomial: 2u(10u25u+9)2u(10u^2 - 5u + 9)
  3. Check Further Factoring: Step Title: Check for Further Factoring\newlineConcise Step Description: Check if the quadratic expression within the parentheses can be factored further.\newlineStep Calculation: The quadratic expression 10u25u+910u^2 - 5u + 9 does not factor nicely since the discriminant (b24ac)(b^2 - 4ac) is negative: (5)24(10)(9)=25360=335(-5)^2 - 4(10)(9) = 25 - 360 = -335.\newlineStep Output: The quadratic expression cannot be factored further.
  4. Subtract 99: Step Title: Subtract 99 from Both Sides\newlineConcise Step Description: To solve the equation, subtract 99 from both sides to set the equation to zero.\newlineStep Calculation: 20u310u2+18u9=020u^3 - 10u^2 + 18u - 9 = 0\newlineStep Output: Adjusted equation: 20u310u2+18u9=020u^3 - 10u^2 + 18u - 9 = 0
  5. Factor Out Common Factor Again: Step Title: Factor Out the Greatest Common Factor Again\newlineConcise Step Description: Factor out the greatest common factor from the adjusted equation.\newlineStep Calculation: The greatest common factor of 20u320u^3, 10u210u^2, 18u18u, and 99 is 11, which does not change the equation.\newlineStep Output: Factored equation: 2u(10u25u+9)9=02u(10u^2 - 5u + 9) - 9 = 0
  6. Check Factoring or Solutions: Step Title: Check for Factoring or Solutions\newlineConcise Step Description: Check if the adjusted equation can be factored or if there are any solutions.\newlineStep Calculation: The equation 2u(10u25u+9)9=02u(10u^2 - 5u + 9) - 9 = 0 does not factor further, and there are no obvious solutions.\newlineStep Output: The equation cannot be factored further and has no simple solutions.
