find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients (g) x^2-9 About the author Natalia
Answer: given, quadratic equation =x^2-9 x^2=9 x=√9,-√9 α=√9 β=-√9 sum of zeros (α+β)=√9+(-√9) =√9-√9 = 0 verification : sum of zeros =-b/a(-coefficient of x/coefficient of x^2) =-0/1=0 product of zeros (αβ)=√9(-√9) =-9 verification : product of zeros =c/a(constant term /coefficient of x^2) =-9/1 =-9 Reply
Answer:
given, quadratic equation =x^2-9
x^2=9
x=√9,-√9
α=√9
β=-√9
sum of zeros (α+β)=√9+(-√9)
=√9-√9
= 0
verification : sum of zeros =-b/a(-coefficient of x/coefficient of x^2)
=-0/1=0
product of zeros (αβ)=√9(-√9)
=-9
verification : product of zeros =c/a(constant term /coefficient of x^2)
=-9/1
=-9
