Answer 1

Answer:

GIVEN:

$p(y) = y ^{2} - 7y + 1$

we know that alpha plus beta is equal to -(coefficient of y)/( coefficient of y^2)

alpha*beta = (constant term)/(coefficient of y^2).

here ;

a is the coefficient of x^2 = 5

b is the coefficient of x = (-7)

c is the constant term = 1

by using this formula we can find the value of one upon alpha plus one upon beta.

please see the attachment.

Answer 2

Answer:

alpha + beta = -b/a

alpha)(beta) = c/a

put these identities in it....
