Q. Rewrite the expression as a product of four linear factors:\newline(5x214x)222(5x214x)+57 \left(5 x^{2}-14 x\right)^{2}-22\left(5 x^{2}-14 x\right)+57 \newlineAnswer:
  1. Identify and Recognize Form: Identify the given expression and recognize that it resembles a quadratic in form, where the variable part is (5x214x)(5x^2 - 14x).\newlineThe expression is: (5x214x)222(5x214x)+57(5x^2 - 14x)^2 - 22(5x^2 - 14x) + 57
  2. Substitution for Simplification: Let u=5x214xu = 5x^2 - 14x. This substitution will simplify the expression into a quadratic form.\newlineThe expression becomes: u222u+57u^2 - 22u + 57
  3. Factor Quadratic Expression: Factor the quadratic expression u222u+57u^2 - 22u + 57. We need to find two numbers that multiply to 5757 and add up to 22-22. The numbers that satisfy these conditions are 19-19 and 3-3, since (19)×(3)=57(-19) \times (-3) = 57 and (19)+(3)=22(-19) + (-3) = -22.
  4. Write Factored Form: Write the factored form of the quadratic using the numbers found in the previous step.\newlineThe factored form is: (u19)(u3)(u - 19)(u - 3)
  5. Substitute Back for u: Substitute back 5x214x5x^2 - 14x for uu in the factored expression.\newlineThe expression becomes: (5x214x19)(5x214x3)(5x^2 - 14x - 19)(5x^2 - 14x - 3)
  6. Further Factor Quadratics: Now, factor each quadratic expression further to find the linear factors.\newlineStarting with 5x214x195x^2 - 14x - 19, we look for two numbers that multiply to 5(19)=955*(-19) = -95 and add up to 14-14.\newlineThe numbers that satisfy these conditions are 19-19 and 55, since (19)5=95(-19) * 5 = -95 and (19)+5=14(-19) + 5 = -14.\newlineHowever, these numbers do not work in this context because they do not allow us to factor the quadratic into two linear factors with integer coefficients. We need to find another approach to factor this quadratic.
