Answer 2

Answer:

Here goes the solution!

p(x) = x2 - 2x - 3

At first substituting p(1),

p(1) = (1)^2 - 2 × 1 - 5

= 1 - 2 - 5

= -6

Now, substituting p(2),

p(2) = (2)^2 - 2 × 2 - 5

= 4 - 4 - 5

= -5

Now, substituting p(-1),

p(-1) = (-1)^2 - 2 × (-1) - 5

= 1 + 2 - 5

= -2

Now substituting p(-2),

p(-2) = (-2)^2 - 2 × (-2) - 5

= 4 + 4 - 5

= 3
