Question

If a, ß are the zeros of the polynomial 24²+7y+5
write the value alfa+ß+Alfa bitta
​

Answer 1

Answer:

Given polynomial 2y2  +7y+5

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

α,β are two zeroes

So, sum of the zeroes =α+β=−  a b=  2 −7

​

 

Product of the zeroes =αβ=  a c =  2 5

​

 

Now just put the values

α+β+αβ=(α+β)+αβ =  2 −7  +  2 5 =  2 −7+25=  2 −2 =−1

∴ So, the required answer is −1.
