Question

factorize the following expression 3(x+y)-9(x+y)2​

Answer 1

Solution~

$3(x + y) - 9(x + y)2 \\ \\ = 3x + 3y - 9x + 9y \times 2 \\ = 3x - 9x + 3y - 18y \\ answer= - 6x - 15y$

Answer 2

$\large\tt\red{\;\;\;3(x + y) - 9(x + y)2}$

$\tt\green{=>\;3x + 3y - 9x + 9y \times 2}$

$\tt\green{ =>\;3x - 9x + 3y - 18y}$

$\tt\green{=>\;\;- 6x - 15y}$
