Answer:

6). 4y²-8y+19

7). -3u²v² + 3uv² + 5uv

Step-by-step explanation:

6).

(12y²- 6y+11) - (8y²+2y-8)

1st step :

12y² - 6y + 11 - 8y²- 2y + 8

2nd step:

(12-8)y² + (-6 - 2)y + (11+8)

3rd step:

4y² + (-6 - 2)y + (11+8)

4th step:

4y² - 8y + (11+8)

7).

(5u²v² - 4uv² - 10uv) - (8u²v² - 7uv² - 15uv)

1st step:

5u²v² - 4uv² - 10uv - 8u²v² + 7uv² + 15uv

2nd step:

(5 - 8) u²v² + (-4 + 7) uv² + (-10 + 15)uv

3rd step:

-3u²v² + (-4 + 7)uv² +(-10 + 15)uv

4th step:

-3u²v² + 3uv² + (-10 + 15)uv
