Answer:

(3x+2+4y)(3x+2-4y)

Step-by-step explanation:

(9x²+12x+4) - 16y²=0

=

(9x²+(6+6)x+4) - (4y)²=0

=

3x(3x+2) +2(3x+2) - (4y)²=0

=

(3x+2)² - (4y)²=0

=

(3x+2+4y)(3x+2-4y)

hope it helped

Answer:

= 9x² - 12x - 16y² + 4

= 9x² - 12x + 4 - 16y²

= (9x² - 12x + 4) - (16y²)

(3x - 2)² - (4y)² → you recognize: a² - b² = (a + b)(a - b)

[(3x - 2) + (4y)] * [(3x - 2) - (4y)]

= (3x - 2 + 4y)(3x - 2 - 4y)

= (3x + 4y - 2)(3x - 4y - 2)
