Question

If the lines represented by the equation ax2bxyy2=0 make angles α and β with the x - axis, then tan(α+β) =



Your Answer
A

Correct Answer
B

Your Answer
C

Your Answer
D

None of these


Solution

The correct option is B


Here the equation is ax2bxyy2=0 and given that m1=tanα and  m2=tanβ and we know that 

m1+m2=b1=tanα+tanβ

and m1m2=a1=tanαtanβ

tan(α+β)=tanα+tanβ1tanαtanβ=b1(a)=b(1+a).
