Answer 2

Answer:

3.

iv) If x=1

p(x) =(x+1) (x-2)

p(1) =(1+1) (1-2)

p(1)=2X(-1) = -2

If x=2

p(x) = (x+1) (x-2)

p(x) = (2+1) (2-2)

p(x) = 4X0 = 0

viii)

The symbol is not clear so

If it's (-) then

p(x) = 2x-1

p(1/2) = 2X1/2 - 1

p(1/2) = 1-1 = 0

If it's (+)

p(x) = 2x+1

p(1/2) = 2X1/2 + 1

p(1/2) = 1+1 = 2

4.

iv) x= (2/3)

viii) x= (-d/c)
