Question

Find the zeroes of the follow;
ing
the zeroes and the coefficients
Quadratic polynomials and verify the relationship betwees the zeroes and the coefficients t^2–15​

Answer 1

Answer:

Q. t²- 15

=> t²-15

=> t²- (√15)

=> (t+√15) (t-√15)

=> t = -√15 , t = √15

=> a = 1 , b = 0 , c = -15

sum of zeros

$\alpha + \beta = - \frac{b}{a}$

=> -√15 + √15 = 0/1

=> 0 = 0

product of zeros

$\alpha \times \beta = \frac{c}{a}$

=> -√15 × √15 = -15/1

=> -15 = -15

That's your answer!
