Sagot :

✎ Problem:

Factor the following:

  1. 8xy - 20x³y
  2. 18y + 30y² - 42y
  3. x - 1
  4. 81 - p²
  5. y² - 20y + 100
  6. x² + 24x + 144
  7. y³ - 1/27
  8. 27x - y

Answers:

For Numbers 1 and 2, this involves factoring the common monomial factor which is the common factor, as a product of numerical and literal coefficients all terms in a given polynomial have in common, such that the common factor can be evenly divided into each term.

  • 1. 8x⁵y⁷ - 20x³y⁶ = 4x³y (2x²y - 5)
  • 2. 18y⁴ + 30y² - 42y = 6y (3y³ + 5y - 7)

For Numbers 3 and 4, this involves factoring the difference of two squares, which is in the form a² - b² = (a + b)(a - b)

  • 3. x⁴ - 1 = (x² + 1)(x² - 1)
  • 4. 81 - p² = (9 + p)(9 - p)

For Numbers 5 and 6, this involves factoring the perfect square trinomial, which is in the form:

  • a² + 2ab + b² = (a + b)²
  • - 2ab + b² = (a - b)²

So:

  • 5. y² - 20y + 100 = (y - 10)²
  • 6. x² + 24x + 144 = (x + 12)²

For Numbers 7 and 8, this involves factoring the sum or difference of two cubes, which is in the form:

  • a³ + b³ = (a + b)(a² - ab + b²)
  • - b³ = (a - b)(a² + ab + b²)

So:

  • 7. y³ - 1/27 = (y - 1/3)(y² + y/3 + 1/9)
  • 8. 27x⁶ - y⁶ = (3x² - y²)(9x³ + 3x²y² + y³)
