Q. Rewrite the expression as a product of four linear factors:\newline(3x27x)216(3x27x)+60 \left(3 x^{2}-7 x\right)^{2}-16\left(3 x^{2}-7 x\right)+60 \newlineAnswer:
  1. Identify Given Expression: Identify the given expression and recognize that it resembles a quadratic in form, where the variable part is (3x27x)(3x^2 - 7x).\newlineThe expression is: (3x27x)216(3x27x)+60(3x^2 - 7x)^2 - 16(3x^2 - 7x) + 60
  2. Transform to Quadratic Form: Notice that the expression can be considered as a quadratic equation in terms of (3x27x)(3x^2 - 7x). Let's denote u=3x27xu = 3x^2 - 7x. The expression becomes:\newlineu216u+60u^2 - 16u + 60
  3. Factor Quadratic Expression: Factor the quadratic expression u216u+60u^2 - 16u + 60. We are looking for two numbers that multiply to 6060 and add up to 16-16. These numbers are 10-10 and 6-6. \newline(u10)(u6)=u216u+60(u - 10)(u - 6) = u^2 - 16u + 60
  4. Substitute Back for uu: Substitute back 3x27x3x^2 - 7x for uu in the factored form.\newline(3x27x10)(3x27x6)(3x^2 - 7x - 10)(3x^2 - 7x - 6)
  5. Factor First Quadratic Expression: Now, factor each quadratic expression further into two linear factors. We start with 3x27x103x^2 - 7x - 10. We need to find two numbers that multiply to (3×10)=30(3 \times -10) = -30 and add up to 7-7. These numbers are 10-10 and +3+3. (3x+3)(x10)(3x + 3)(x - 10)
  6. Factor Second Quadratic Expression: Next, factor the second quadratic expression 3x27x63x^2 - 7x - 6. We need to find two numbers that multiply to (3×6)=18(3 \times -6) = -18 and add up to 7-7. These numbers are 9-9 and +2+2. (3x+2)(x3)(3x + 2)(x - 3)
  7. Combine Linear Factors: Combine all the linear factors to express the original expression as a product of four linear factors.\newline(3x+3)(x10)(3x+2)(x3)(3x + 3)(x - 10)(3x + 2)(x - 3)
