" If "sec theta+tan theta=1," then root of the equation "(a-2b+c)x^(2)+(b-2c+a)x+(c-2a+b)=0" is "

If sectheta+ tantheta = 1 , then root of the equation (a-2b + c)x^2 +(b-2c+ a)x+(c-2a+b) = 0 is:

If sec theta+tan theta=1, then one root of the eqection a(b-c)x^(2)+b(c-a)x+c(a-b)=0 is (A) tan theta(B)sec theta(C)cos theta(D)sin theta

The roots of the quadratic equation (a+b-2c)x^(2)+(2a-b-c)x+(a-2b+c)=0 are

If a lt c lt b then the roots of the equation (a−b)x^2 +2(a+b−2c)x+1=0 are

If a,b,c in Q, then roots of the equation (b+c-2a)x^(2)+(c+a-2b)x+(a+b-2c)=0 are

if one of the root of the equation a(b-c)x^(2)+b(c-a)x+c(a-b)=0 is 1,the other root is

If one of the roots of the equation a(b-c)x^(2)+b(c-a)x+c(a-b)=0 is 1, the other root is

If a sec theta + b tan theta = c then (a tan theta + b sec theta)^(2)=
