In `Delta PQR` , `/_R=pi/4`, `tan(P/3)`, `tan(Q/3)` are the roots of the equation `ax^2+bx+c=0`, then

In a Delta PQR, /_R=(pi)/(2) .if tan(P/2) and tan(Q/2) are the roots of the equation ax^(2)+bx+c=0 ,then relation between a, b and c

2x^(2) + 3x - alpha - 0 " has roots "-2 and beta " while the equation "x^(2) - 3mx + 2m^(2) = 0 " has both roots positive, where " alpha gt 0 and beta gt 0. Delta PQR, angleR=pi/2. " If than "(P/2) and tan (Q/2) " are the roots of the equation " ax^(2) + bx + c = 0 , then which one of the following is correct ?

If a+b+c=0 then roots of the equation 3ax^(2)+4bx+5c=0 are

If, in a /_\PQR , right angled at R, tan (P/2) and tan (Q/2) are the roots of the equation ax^(2) + bx + c = 0 , a!= 0 , then

In a triangle PQR, angleR = pi //2 . If tan (P/2) and tan (Q/2) are the roots of the equations ax^(2) + bx + c = 0 where a ne 0 , then
