Q. Rewrite the expression as a product of four linear factors:\newline(x23x)222(x23x)+72 \left(x^{2}-3 x\right)^{2}-22\left(x^{2}-3 x\right)+72 \newlineAnswer:
  1. Identify and Set Up: Let's identify the given expression and set it up for factoring:\newlineThe expression is a quadratic in terms of x23xx^2 - 3x, which can be represented as:\newlineLet y=x23xy = x^2 - 3x\newlineThen the expression becomes:\newliney222y+72y^2 - 22y + 72\newlineNow we will factor this quadratic equation.
  2. Find Factors: We need to find two numbers that multiply to 7272 and add up to 22-22. These numbers are 18-18 and 4-4 because 18×4=72-18 \times -4 = 72 and 18+4=22-18 + -4 = -22.\newlineSo we can factor the quadratic as:\newline(y18)(y4)(y - 18)(y - 4)
  3. Substitute and Simplify: Now we substitute back x23xx^2 - 3x for yy to get: (x23x18)(x23x4)(x^2 - 3x - 18)(x^2 - 3x - 4)
  4. Factor x23x18x^2 - 3x - 18: Next, we need to factor each quadratic expression further. Starting with x23x18x^2 - 3x - 18, we look for two numbers that multiply to 18-18 and add up to 3-3. These numbers are 6-6 and +3+3. So we can factor x23x18x^2 - 3x - 18 as: (x6)(x+3)(x - 6)(x + 3)
  5. Factor x23x4x^2 - 3x - 4: Now, we factor x23x4x^2 - 3x - 4 by finding two numbers that multiply to 4-4 and add up to 3-3. These numbers are 4-4 and +1+1. So we can factor x23x4x^2 - 3x - 4 as: (x4)(x+1)(x - 4)(x + 1)
  6. Write as Product: Finally, we write the original expression as a product of four linear factors: x - \(6)(x + 33)(x - 44)(x + 11)\
