Answer 1

Answer:

1) a) 3 b) -1 c) π/2

2)a)3 b)2 c) 1 d) 0

3) a) 7

b)5+3+7 = 15

c)20-6+7 = 21

4) a) -7/3 b) -3 c) 0

5)a putting x = -2 we get,

(-8)+3*4-3*2+1 = -1

b) putting x = 1/2 we get now ,

1/8+3/4+3/2+1 = 27/8

6) put x = 3/2 and solve yourself, ( sab पका पकाया मत लो, बच्चो को पढ़ा रही तो खुद भी कुछ करो )

7) if we put x = 2 , we get 2*4-2-6 = 0, so yes it's a factor .

9) put x = -1 , we get = -2+1+2-1 = 0, yes it's a factor .

10) a) 1+1+k = 0,

k = -2

b) k-√2+1 = 0

k = √2-1

c) 2k-3 = 0

k = 3/2

last one try yourself now, it's your homework , not your students .
