Full solution

Q. Factor completely 7x521x4+14x3=7x^5-21x^4+14x^3=
  1. Identify GCF: Identify the greatest common factor (GCF) of the terms.\newlineThe terms are 7x57x^5, 21x4-21x^4, and 14x314x^3.\newlineThe GCF of the coefficients (7,21,14)(7, -21, 14) is 77.\newlineThe GCF of the powers of xx (x5x^5, x4x^4, x3x^3) is x3x^3.\newlineSo, the GCF of the entire expression is 21x4-21x^400.
  2. Factor out GCF: Factor out the GCF from each term.\newline7x521x4+14x3=7x3(x23x+2)7x^5 - 21x^4 + 14x^3 = 7x^3(x^2 - 3x + 2)
  3. Factor quadratic: Factor the quadratic expression inside the parentheses.\newlineWe need to find two numbers that multiply to 22 (the constant term) and add up to 3-3 (the coefficient of the xx term).\newlineThe numbers that satisfy these conditions are 1-1 and 2-2.\newlineSo, the quadratic x23x+2x^2 - 3x + 2 can be factored as (x1)(x2)(x - 1)(x - 2).
  4. Write final form: Write the final factored form by combining the GCF and the factored quadratic. \newline7x3(x23x+2)=7x3(x1)(x2)7x^3(x^2 - 3x + 2) = 7x^3(x - 1)(x - 2)
