Question

3(x+2)^2 - 5(x+2) ^2​

Answer 1

Answer:

⇢ -2x² + -8x+ -8

Step-by-step explanation:

⇢ 3(x + 2)2 - 5(x + 2)²

⇢ 3x² + 12x + 12 + -5x² + -20x + -20

Now, combining like terms:

⇢ 3x² + 12x + 12 + -5x² + -20x + -20

⇢ (3x² + -5x²) + (12x + -20x) + (12 + -20)

⇢ -2x² + -8x+ -8

Therefore, this is the required answer.
