Answer 1

sorry I m in ICSE board

Answer 2

Answer:

b/ac

Step-by-step explanation:

i will replace alpha by A and beta by B

1 / (aA +b) + 1 / (aB + b)

taking lcm

(aB + b + aA + b ) / (a²AB + abA + abB + b²)

= [a(A+B) + 2b ] / [a²AB + ab(A+B) + b²]

= [ a(-b/a) + 2b] / [a²(c/a) + ab(-b/a) +b²]

= [ b ] / [ac -b² +b²]

= b / ac

thats the answer

hope this helps
