Q. Rewrite the expression as a product of four linear factors:\newline(6x211x)212(6x211x)85 \left(6 x^{2}-11 x\right)^{2}-12\left(6 x^{2}-11 x\right)-85 \newlineAnswer:
  1. Identify and Recognize Quadratic Form: Identify the given expression and recognize that it resembles a quadratic in form, where the variable part is (6x211x)(6x^2 - 11x) instead of a simple xx. The expression is a quadratic in (6x211x)(6x^2 - 11x):(6x211x)212(6x211x)85(6x^2 - 11x)^2 - 12(6x^2 - 11x) - 85
  2. Set Substitution for Simplification: Let's set a substitution to simplify the expression. Let u=6x211xu = 6x^2 - 11x. The expression then becomes:u212u85u^2 - 12u - 85 This is a quadratic equation in terms of uu.
  3. Factor Quadratic Equation: Factor the quadratic equation u212u85u^2 - 12u - 85. We need to find two numbers that multiply to 85-85 and add up to 12-12. These numbers are 17-17 and 55. \newline(u17)(u+5)=0(u - 17)(u + 5) = 0
  4. Substitute Back and Factor in Terms of x: Now, substitute back 6x211x6x^2 - 11x for uu to get the factors in terms of xx:(6x211x17)(6x211x+5)=0(6x^2 - 11x - 17)(6x^2 - 11x + 5) = 0
  5. Factor First Quadratic: Each of these quadratic factors can be further factored into linear factors. We will start with the first one: 6x211x176x^2 - 11x - 17. To factor this, we need to find two numbers that multiply to 6×17=1026 \times -17 = -102 and add up to 11-11. These numbers are 17-17 and 66. \newline(3x17)(2x+1)=6x211x17(3x - 17)(2x + 1) = 6x^2 - 11x - 17
  6. Factor Second Quadratic: Now, factor the second quadratic: 6x211x+56x^2 - 11x + 5. We need to find two numbers that multiply to 6×5=306 \times 5 = 30 and add up to 11-11. These numbers are 6-6 and 5-5. \newline(3x5)(2x1)=6x211x+5(3x - 5)(2x - 1) = 6x^2 - 11x + 5
  7. Combine Linear Factors: Combine all the linear factors to express the original expression as a product of four linear factors: (3x17)(2x+1)(3x5)(2x1) (3x - 17)(2x + 1)(3x - 5)(2x - 1)
