Answer:

i) Zeroes of the polynomial = +√15 and -√15.

ii) Relationship between the zeroes and coefficient of the polynomial is verified.

Step-by-step explanation:

15 can be written as (√15)²

t²-(√15)² = (t+√15)(t-√15)

Take t+√15 = 0

t = -√15

Then, take t-√15 = 0

t = √15

Therefore √15 and -√15 are the zeroes of the polynomial.

Now, the quadratic equation that is given:

t²-0t-15

Sum of the zeroes (α+β)= -b/a = -√15+√15 = 0

= -(-0)/1

=0

Product of the zeroes (α*β) = c/a = -15/1 = -15

= -√15 * √15

=-15

Hence, the relationship is also verified.

Step-by-step explanation:

t^2-15=0

t2-\sqrt{15]^2 = 0

[t+\sqrt15]    [t-\sqrt15]=0

t= -\sqrt15     t= \sqrt15

∝= -\sqrt15       β=\sqrt15

∝+β= -\sqrt15+15=0

-b/a=o

∴ ∝+β = -b/a

∝β = -\sqrt15*\sqrt15= -15

c/a= -15/1= =15

∴∝β=c/a
