Answer:

= 6x +9

Step-by-step explanation:

1. you need to multiply -3 by x² + 2x - 3

so you got -3x² -6x + 9

2. Then, you need to multiply 3 by (x²+4x)

= 3x² + 12x

3. -3x² - 6x + 9 + 3x² + 12x

4. then you need to solve with the same

= - 3x² + 3x²

= 0

= - 6x + 12x

= 6x

5. lastly you will got the answer.
