Answer 1

Answer:

$- 39xy + 12 {y}^{2}$

Step-by-step explanation:

1) Simplify 6x × 2y to to 12xy.

$12xy - 3xy - 24xy \times 2 + 12 {y}^{2}$

2) Simplify 24xy × 2 to 48xy.

$12xy - 3xy - 48xy + 12 {y}^{2}$

3) Collect like terms.

$(12xy - 3xy - 48xy) + 12 {y}^{2}$

4) Simplify.

$- 39xy + 12 {y}^{2}$

Thus, The answer is -39xy + 12y².
