Q. Rewrite the expression as a product of four linear factors:\newline(x2x)222(x2x)+40 \left(x^{2}-x\right)^{2}-22\left(x^{2}-x\right)+40 \newlineAnswer:
  1. Identify Structure: Let's first identify the structure of the given expression and see if it resembles any known algebraic identities. The expression is:\newline(x2x)222(x2x)+40(x^2 - x)^2 - 22(x^2 - x) + 40\newlineThis looks like a quadratic equation in the form of (a22ab+b2)(a^2 - 2ab + b^2), where a'a' is (x2x)(x^2 - x) and b'b' is some number we need to find. To factor it, we will consider it as a quadratic in terms of (x2x)(x^2 - x).
  2. Substitute and Simplify: Let's denote u=x2xu = x^2 - x. Then the expression becomes:\newlineu222u+40u^2 - 22u + 40\newlineNow we need to factor this quadratic expression.
  3. Factor Quadratic Expression: To factor the quadratic expression u222u+40u^2 - 22u + 40, we need to find two numbers that multiply to 4040 and add up to 22-22. These numbers are 20-20 and 2-2 because (20)×(2)=40(-20) \times (-2) = 40 and (20)+(2)=22(-20) + (-2) = -22.\newlineSo we can write the quadratic as:\newline(u20)(u2)(u - 20)(u - 2)
  4. Factor First Quadratic: Now we substitute back x2xx^2 - x for uu in the factored form to get:\newline(x2x20)(x2x2)(x^2 - x - 20)(x^2 - x - 2)\newlineNow we need to factor each of these quadratic expressions further.
  5. Factor Second Quadratic: We will factor the first quadratic expression x2x20x^2 - x - 20. We need to find two numbers that multiply to 20-20 and add up to 1-1 (the coefficient of xx). These numbers are 5-5 and 44 because (5)×4=20(-5) \times 4 = -20 and (5)+4=1(-5) + 4 = -1.\newlineSo we can write the first quadratic as:\newline(x5)(x+4)(x - 5)(x + 4)
  6. Final Linear Factors: Next, we will factor the second quadratic expression x2x2x^2 - x - 2. We need to find two numbers that multiply to 2-2 and add up to 1-1 (the coefficient of xx). These numbers are 2-2 and 11 because (2)×1=2(-2) \times 1 = -2 and (2)+1=1(-2) + 1 = -1.\newlineSo we can write the second quadratic as:\newline(x2)(x+1)(x - 2)(x + 1)
  7. Final Linear Factors: Next, we will factor the second quadratic expression x2x2x^2 - x - 2. We need to find two numbers that multiply to 2-2 and add up to 1-1 (the coefficient of xx). These numbers are 2-2 and 11 because (2)×1=2(-2) \times 1 = -2 and (2)+1=1(-2) + 1 = -1.\newlineSo we can write the second quadratic as:\newline(x2)(x+1)(x - 2)(x + 1)Now we have factored the original expression into four linear factors:\newline(x5)(x+4)(x2)(x+1)(x - 5)(x + 4)(x - 2)(x + 1)\newlineThis is the product of four linear factors for the given expression.
