Question

if alpha and beta are the zeroes of the polynomial x2-4x+3 then 1 /alpha+1/beta =
​

Answer 1

Answer:

4/3

Step-by-step explanation:

We know that,

• alpha +beta=-b/a
• -(-4)/1=4(here a=2 and b=-4)
• 4

also, alpha * beta =c/a

• 3/1(here c=3)
• 3

now 1/ alpha +1/ beta

• =alpha + beta / alpha*beta ( alpha beta ka lcm liya hai)
• 4/3 (alpha +beta = 4 and alpha *beta =3)

Hence, 1/ alpha + 1/ beta =4/3
