Question

if alfa,beta of the zeros of the polynomial 2y^+7y+5,write the value of alfa+beta+alfa×beta.​

Answer 1

if alfla is a

if beta is b then

a+b= -b/a====-7/2

a.b=c/a======5/2
ans=-1


this is correct
pls make me as a brainlist answer

Answer 2

Answer:

2y^2 +7y +5

That means

a= 2

b= 7

c= 5

We can use this:

Alpha + Beta = -b/a

= -7/5

Alpha X Beta = c/a

= 5/2

So

-7/5 + 5/2

-14+25/10(taking lcm)

11/10

1.1
