Question

If £β are solution of sin ^2x+ aSinx +b and Cos^2 x + cCos x+ d=0
(α - β ≠ nπ) then sin [£+β]
equals​

Answer 1

Answer:

2ac/a^2+c^2

Step-by-step explanation:

Generally alpha, beta are roots

Therefore sin(alpha) and sin(beta) are roots ie

Sin(alpha) +sin(beta) =-a

Cos(alpha)+cos(beta)=-c

Apply transformations

You will get the answer
