Q. Rewrite the expression as a product of four linear factors:\newline(x23x)214(x23x)+40 \left(x^{2}-3 x\right)^{2}-14\left(x^{2}-3 x\right)+40 \newlineAnswer:
  1. Identify Expression: Let's identify the expression we need to factor: \newline(x23x)214(x23x)+40(x^2 - 3x)^2 - 14(x^2 - 3x) + 40\newlineNotice that this is a quadratic in form, where (x23x)(x^2 - 3x) is like a single variable. Let's substitute u=x23xu = x^2 - 3x to make it clearer.
  2. Rewrite in terms of uu: Rewrite the expression in terms of uu:u214u+40u^2 - 14u + 40Now we have a quadratic equation in uu that we can factor.
  3. Factor Quadratic Equation: Factor the quadratic equation: \newlineu214u+40=(u10)(u4)u^2 - 14u + 40 = (u - 10)(u - 4)\newlineWe found two factors of the quadratic equation.
  4. Substitute back for xx: Substitute back x23xx^2 - 3x for uu:
    (u10)(u4)=(x23x10)(x23x4)(u - 10)(u - 4) = (x^2 - 3x - 10)(x^2 - 3x - 4)
    Now we have the expression in terms of xx again, but we need to factor each quadratic further.
  5. Factor First Quadratic: Factor the first quadratic x23x10x^2 - 3x - 10: We look for two numbers that multiply to 10-10 and add to 3-3. These numbers are 5-5 and 22. x23x10=(x5)(x+2)x^2 - 3x - 10 = (x - 5)(x + 2)
  6. Factor Second Quadratic: Factor the second quadratic x23x4x^2 - 3x - 4: We look for two numbers that multiply to 4-4 and add to 3-3. These numbers are 4-4 and 11. x23x4=(x4)(x+1)x^2 - 3x - 4 = (x - 4)(x + 1)
  7. Combine Linear Factors: Combine all the linear factors to express the original expression:\newline(x23x10)(x23x4)=(x5)(x+2)(x4)(x+1)(x^2 - 3x - 10)(x^2 - 3x - 4) = (x - 5)(x + 2)(x - 4)(x + 1)\newlineWe have rewritten the expression as a product of four linear factors.
