Question

a and B are zeroes of the polynomial
f (x) = x2-5x+k such that a-B=1
then find the valul
value of k​

Answer 1

Answer:

k=6

Step-by-step explanation:

alpha and beta are zeros of the polynomial f(x)=x^2-5x+k.

let alpha=a &beta=b

a+b=-(-5/1)=5;ab=k/1=k

Now, a-b=1 squaring both sides

(a-b)^2=1

(a+b)^2-4ab=1

25-4k=1

4k=24

k=6.

Answer 2

Step-by-step explanation:

such that a-B=1

then find the valul

value
