If `3a-2b + 5c = 0`. then family of straight lines `ax + by + c =0` are always concurrent at a point whose co-ordinates is `(alpha, beta),` then the values of `5(alpha-beta)`

If a^2+b^2-c^2-2ab = 0 , then the family of straight lines ax + by + c = 0 is concurrent at the points

If a + 2b + 3c = 0, the family of straight lines ax + by + c = 0 passes through a fixed point, find the co-ordinates of fixed point.

(i) If a, b, c, are in A.P. then show that ax….+….by +c=0 passes through a fixed point. Find then fixed point. (ii) If 9a^(2)+16b^(2)-24ab-25c^(2)=0, then the family of straight lines ax+by+0 is concurrent at the point whose co-ordinates are given by "________" (iii) If 3a+4b-5c=0, then the family of straight lines ax+by+c=0 passes through a fixed point. Find the coordinates of the point.

Two roots of the equation ax^2 +bx +c=0 is alpha,beta then find the value of alpha^3 + beta^3

If alpha and beta are the roots of the equation ax^(2)+bx+c=0, then the value of alpha^(3)+beta^(3)

If alpha and beta are the roots of equation ax^2 + bx + c = 0, then the value of alpha/beta + beta/alpha is

if alpha and beta are the roots of ax^(2)+bx+c=0 then the value of {(1)/(a alpha+b)+(1)/(a beta+b)} is
