6x - (x + 3)^2
= 6x - (x + 3)(x + 3)
= 6x - (x^2 + 3x + 3x + 9)
= 6x - x^2 - 3x - 3x - 9
= 6x - 3x - 3x - x^2 - 9
= 3x - 3x - x^2 - 9
= 0 - x^2 - 9
= 0 - 9 - x^2
= -9 - x^2
= 6x - (x + 3)(x + 3)
= 6x - (x^2 + 3x + 3x + 9)
= 6x - x^2 - 3x - 3x - 9
= 6x - 3x - 3x - x^2 - 9
= 3x - 3x - x^2 - 9
= 0 - x^2 - 9
= 0 - 9 - x^2
= -9 - x^2
