2. 16x²-81y²

3. X³ + 27

4. 4x² + 12x + 9

5. x² + 2x - 15

THANKS (｡♡‿♡｡)​

Write YOUR SOLUTION PLEASE

Answer 1

Ans

1) 7x³y (5x²y + 3x + 2y)

find the gcf of the coeficients and that is 7, then annex the variables with the lowest exponent

for x that is x³ an for y that is y → 7x³y, obtain the other factor by long division
