Question

Given polynomial x square - 7 x + k is also given that alpha minus beta is equals to 1 find the value of k

Answer 1

Answer:

Step-by-step explanation:

ALPHA -BETA=1.....(1)

ALPHA+BETA=7

_______________

2ALPHA=8

ALPHA=4

USE THIS VALUE IN EQ1

4-BETA=1

-BETA=-3

BETA=3

X^2-7X+K

ALPHA*BETA=c/a

Using value of alpha n beta

4*3=K

K=12 is the answer
