Answer 1

Answer:

Q1. question is not clear

Q2. 3

Q. 3.(0, 0)

Q. 5.quadrant 2

sorry i know only some questions

Answer 2

Answer:

1. Incomplete

2. Degree --- 3

3.(0,0)

4. (x+3) + (-x-3) = 0

5. 2nd quadrant

7. 3x - 9 = 0

3x = 9

x = 3

8.(4,0)

9.215 x 0 = 0

10. On putting x = -1

We get,

-a +(-1)^2 -2(-1) +4a - 9 = 0

3a - 6 = 0

3a = 6

a = 2
