Question

For questions 2 z 3. simplify each polynomial
2. 3x²+6-2x+5x-4x²+9
3. 2x²+6x-7x+8-3x²+1​

Answer 1

2.
`-x^(2) +3x+15`

3.
`-x^(2) -x+9`

Explanation:

We add like terms together to simplify

2. 3x²-4x²= -x² -2x+5x= 3x 6+9= 15 all equal to -x²+3x+15

3. 2x²-3x²= -x² 6x-7x= -x 8+1=9 all equal to -x²-x+9
