Question

t²–15 find the zeroesof this quadratic polynomial and verify the relationship between the zeroes and the coefficient ​

Answer 1

t²-15= 0

t²= 15

t= ±√15

t= √15,-√15

Sum of zeroes= √15-√15=0 = -(coefficient of x)/coefficient of x²

Product of zeroes =(√15)×(-√15)= -15 =Constant term/ coefficient of x²
