Q7. Find the zeroes of the following quadratic polynomials and verify the relationship
between the zeroes and the coefficients.
mark t t square - 15 ​

Answer 1

Step-by-step explanation:

the equation is

t² - 15 = 0

= > t² = 15

=> t = ±√15

so t = +√15 , - √15

now

we have a = 1 b = 0 and c = -15

so sum of roots must be 0 because -b/a = 0

+√15 + (-√15) = 0

and product of roots must be -15 because c/a = -15/1 = -15

(+√15) * (-√15) = -15

hence verified.
