Question

the heroes alpha and beta of a polynomial x square - 7 x + K such that Alpha minus beta is 1 Alpha minus beta is equals to 1 find the value of k​

Answer 1

Explanation:

alpa - beta = 1

alpa = beta +1

alpa + beta = -b/a

beta + 1 + beta = -(-7)

2beta = 6.

beta = 3

then alpa = 3+1 =4

k = alpa × beta = c/a

k = 3×4

k= 12
