Question

if alpha and beta are the zeros of the polynomial P(x)=x²-9 find the value of alpah × beta (alpah +beta) ​

Answer 1

Answer:

the value of alpha plus beta is 0

We can write

x²-0x-9

x²+(alpha + beta)x-(alpha *beta)

hence alpha+ beta = 0

Answer 2

Step-by-step explanation:

Hey!!!

Good Afternoon

________

let p(x) = x² - 9

=> x² - 9 = 0

=> x² = 9

=> x = 3 or x = -3

let

\alpha = 3 \: and \: \beta = - 3α=3andβ=−3

To find

= > \beta ( \alpha + \beta )=>β(α+β)

Let's replace values

=> -3(3 - 3)

=> 0 <<<<<< Answer
