(Q9)Draw the graphs of the given polynomial and find the zeros justify the answer P(x) = x2 - 1.

Given polynomial p(x) = x2 - 1

List of the values of p(x):

x -2 -1 0 1 2
x2
1
p(x) -
(x,y) (-,) (-,) (,-) (,) (,)

Now lets locate the points listed above on a graph paper and draw the graph,

Result: We observe that the graph cuts the X-axis at (-1,0) and (1,0).

So the zeros of the polynomial are 1 and 1.

Justification:

p(x) = (x+) (x-) = 0

x+ = 0 and x- = 0

x = -and x =
