Q. Factor completely.\newline5x225x30 -5 x^{2}-25 x-30 \newlineAnswer:
  1. Identify common factor: Identify the common factor in all terms.\newlineThe polynomial is 5x225x30-5x^2 - 25x - 30. All terms have a common factor of 5-5.
  2. Factor out common factor: Factor out the common factor.\newlineFactor out 5-5 from each term to get 5(x2+5x+6)-5(x^2 + 5x + 6).
  3. Factor quadratic expression: Factor the quadratic expression.\newlineNow we need to factor the quadratic x2+5x+6x^2 + 5x + 6. We are looking for two numbers that multiply to 66 (the constant term) and add up to 55 (the coefficient of the xx term).\newlineThe numbers 22 and 33 satisfy these conditions because 2×3=62 \times 3 = 6 and 2+3=52 + 3 = 5.
  4. Write factored form: Write the factored form of the quadratic.\newlineThe factored form of x2+5x+6x^2 + 5x + 6 is (x+2)(x+3)(x + 2)(x + 3).
  5. Combine with common factor: Combine the factored quadratic with the common factor.\newlineThe final factored form of the original polynomial is 5(x+2)(x+3)-5(x + 2)(x + 3).
