Question

if alpha and beta are zeroes of the polynimial f(x)=6x^2+x-2 find alpha-betaif alpha and beta are zeroes of the polynimial f(x)=6x^2+x-2 find alpha-beta

Answer 1

Answer:

7/6

Step-by-step explanation:

$\alpha - \beta \: = \: \frac{\sqrt{discriminant}}{a}$

here 'a' = co-efficient of polynomial

D ( discriminant ) = b^2 - 4ac

= (1)^2 - 4 × 6 × (-2)

= 1 + 48

= 49

So ,

$\alpha - \beta \: = \frac{\sqrt{49} }{6} = \frac{7}{6}$
