Question

Find k, if one root of x^2+21x+k=0 is 1 more than other root

Answer 1

Answer:

Step-by-step explanation:

Let the roots be alpha and beta.

By given alpha =. 1+beta ------(1)

Sum of the roots = -21 ------(2)

Product of the roots = k -----(3)

From (2) , 1+beta + beta= -21

1+2 beta =-21

Beta = -11

Alpha = -10

The value of k is 110
