Full solution

Q. Factor completely.\newline3x2+6x+9=-3x^{2}+6x+9=
  1. Identify quadratic trinomial and coefficients: Identify the quadratic trinomial and its coefficients.\newlineThe given quadratic trinomial is 3x2+6x+9-3x^2 + 6x + 9, where the coefficients are 3-3 for x2x^2, 66 for xx, and 99 as the constant term.
  2. Factor out greatest common factor: Factor out the greatest common factor (GCF) from the trinomial.\newlineThe GCF of 3x2-3x^2, 6x6x, and 99 is 33. However, since the leading coefficient is negative, we will factor out 3-3 to keep the squared term positive in the resulting trinomial.\newlineFactoring out 3-3 gives us: 3(x22x3)-3(x^2 - 2x - 3).
  3. Factor trinomial inside parentheses: Factor the trinomial inside the parentheses.\newlineWe need to find two numbers that multiply to give 3-3 (the constant term) and add to give 2-2 (the coefficient of xx).\newlineThe numbers that satisfy these conditions are 3-3 and +1+1.\newlineTherefore, we can write the trinomial as: 3((x3)(x+1))-3((x - 3)(x + 1)).
  4. Write final factored form: Write the final factored form.\newlineThe factored form of the quadratic expression is: 3(x3)(x+1)-3(x - 3)(x + 1).
