Answer 2

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
