Question

Polynomial f ( x) =x ^3 8 x ^2 + 5 are alpha - beta, alpha and alpha + beta then find the value of k

Answer 1

Answer:

first read ur question is wrong there equation is not complete check it out...

Step-by-step explanation:

f( x) = kx³- 8x²+5

roots of equation are α-β, α ,α+β

then ,

sum of roots = -(-8k)

sum of roots = α-β+α+α+β

= 3α

8k = 3α

k = 3α/8

mark me as a brainlist ......plsss☺☺
