Question

what is the factored form of the polynomial?

(x^2 - 12x + 27)?

( ) ((x + 4)(x + 3))
( ) ((x - 4)(x + 3))
( ) ((x + 9)(x + 3))
( ) ((x - 9)(x - 3))

Explanation:

Identify the coefficients of the quadratic trinomial

$$ a = 1, \quad b = -12, \quad c = 27 $$

Find two numbers that multiply to \(c\) and add to \(b\)

$$ LATEXBLOCK0 $$

Write the trinomial in its factored form

$$ x^2 - 12x + 27 = (x - 9)(x - 3) $$

Answer:

  • (A) \((x + 4)(x + 3)\)
  • (B) \((x - 4)(x + 3)\)
  • (C) \((x + 9)(x + 3)\)
  • (D) \((x - 9)(x - 3)\) (Correct answer)
