Question

Find the zeroes of the polynomial 2x^2-10 and verify the relationship between the zeroes and the coefficient ?

Answer 1

2x^2 - 10
2x^2 = 10
x^2 = 10/2
x^2 = 5
x = plus minus under root 5

Zeros
x =+ root 5. x = - root 5

Sum = -b/a = -0/2 = 0

Product = c/a = -10/2 = -5

Verification :

Sum = alpha + beta = root5 + (-root5)
= root5 - root5 = 0

Product = alpha.beta = root5.(-root5)
= -5

Hence Verified !
