Question

If alpha and beta are the zeroes of the polynomial x^2-6x+a find alpha if beta = -2

Answer 1

hey brainy user

here is ur answer,

Answer:

answer is 8

Step-by-step explanation:

$\alpha \\ \beta \\ are \: zeroes \: of \: the \: polynomial \: {x}^{2} - 6x + a$

$\beta = - 2$

$\alpha + \beta = \frac{ - b}{a}$

$\alpha - 2 = \frac{ - ( - 6)}{1}$

$\alpha = 8$

hope the answer helps
