pls answer fastttttt very fast plspls ​

Answer 1

Answer:

$(x - 7y {)}^{2} (5x - y {)}^{2}$

Step-by-step explanation:

$(3x - 4y {)}^{2} - (2x + 3y {)}^{2} \\ since \: = {a}^{2} - {b}^{2} = (a - b)(a + b) \\ = )[3x - 4y - (2x + 3y)][3x - 4y + (2x + 3y)] \\ = )(3x - 4y - 2x - 3y)(3x - 4y + 2x + 3y) \\ = )(x - 7y)(5x - y)$

Hope It Helped
