1. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
(v) t² – 15

(v) t² – 15
Factorize the equation
t² – 15 = 0
Add 15 both side we get
t² = 15
Take square root both side
t= ± √15
First zero is                                √15
second zerois                           -  √15
Sum of zero               √15 - √15        = 0
Product of zero           √15 x -√15      = -15
Compare the equation with at² + bt  +c = 0
We get
a = 1, b = 0, c = -15

Sum  of zero              -b/a     = -(0/1)  = 0
Product of zero           c/a      =  -15/1 =  -15
