Question

I don't need help with this but I got so many points and I don't know what to do with them:) -4x²-9+10x+16x²-12x

Answer 1

• 12x² - 2x - 9

Step-by-step Solution:

• -4x² - 9 + 10x + 16x² - 12x

Combining like terms:

• => (-4x² + 16x²) + (10x - 12x) - 9

Solving:

• => (12x²) + (-2x) - 9

Opening the Brackets:

• => 12x² - 2x - 9

We can conclude that 12x² - 2x - 9 is the simplified answer.
