Question

if alpha and beta are zeroes of the polynomial P(x) = x^2 -5x +c and alpha - beta =1 , the value of c is ​

Answer 1

Answer:

C=6

We know that alpha plus beta is - b/a

1. Alpha x beta is plus c/a.
2. Substitute - 5in place of b and 1 in place of a.
3. You get the value of alpha plus beta. Add alpha plus beta and given alpha minus beta.
4. Beta is canceled and u get alpha value as 3
5. Substitute it in any equation and u get beta value.
6. Substitute alpha and beta values in step 2.
