Question

If and are the zeroes of a polynomial 22 + 7 + 5 then find the value of + +

Answer 1

$\huge \fbox \purple{❥Answer}$

Given polynomial 2y 2 +7y+5

Here a=2,b=7,c=5

α,β are two zeroes

So, sum of the zeroes =α+β= − b/a

= -7/2

Product of the zeroes =αβ= c/a

= 5/2

Now just put the values

α+β+αβ=(α+β)+αβ

= -7/2+5/2

= -7+5/2

= −2/2

= −1

∴ So, the required answer is −1.
