Answer 2

Answer:

(3x + 9y + 2)(x + 3y - 2)

Step-by-step explanation:

ax² + bx + c = a( x - $x_{1}$ )( x - $x_{2}$ )

$x_{1}$ and $x_{2}$ are zeros of quadratic function.

~~~~~~~~~~

3( x + 3y )² - 4( x + 3y ) - 4

Let ( x + 3y ) = t , then

3t² - 4t - 4 = 3( t + $\frac{2}{3}$ )( t - 2) = (3t + 2)(t - 2)

[3(x + 3y) + 2][(x + 3y) - 2] = (3x + 9y + 2)(x + 3y - 2)
