Question

The zeroes of the polynomial x^2-2x-3 are 3 and -1.

Answer 1

Answer:

Yes, you are correct 3,-1 are the solutions of the given equation

Step-by-step explanation:

x=3

(3)^2 -2(3)-3

9-6-3

= 0

when x=-1

(-1)^2-2(-1)-3

1+2-3

3-3

=0

Answer 2

Answer:

True, zeroes of the polynomial x²-2x-3 are 3 & -1

Step-by-step explanation:

p(x) = x² -2x -3

p(3) = (3)² -2(3) -3

= 9 -6 -3

= 9 -9

= 0

p(x) = x²-2x -3

p(-1) = (-1)² - 2(-1) -3

= 1 +2 -3

= 3 -3

= 0
