Answer 2

Answer:

ANSWER IS THIS

1. 2x
2. 2x 2
3. 2x 2 −3y+3x
4. 2x 2 −3y+3x 2
5. 2x 2 −3y+3x 2 +5x
6. 2x 2 −3y+3x 2 +5x 2
7. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y
9. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x
10. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2
11. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7
12. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,
14. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,10(−1)
15. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,10(−1) 2
16. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,10(−1) 2 −2(−1)−2−7
18. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,10(−1) 2 −2(−1)−2−7= 10+2−2−7
20. 2x 2 −3y+3x 2 +5x 2 +5x−7−7x+2y =10x 2 −2x−y−7At x=−1 and y=2,10(−1) 2 −2(−1)−2−7= 10+2−2−7 =3
