If a,b and c are three consecutive odd integers and the variable line ax+by+c=0 always passes through `(alpha,beta)` then `| alpha+beta|` is

If a, b, c are three consecutive odd Integers, then the line ax - by + c = 0 passes through the point 1) (-1,2) 2) (1,2) 3) (2, 3) 4) (0, 1)

If alpha and beta are two fixed complex numbers, then the equation z=aalpha+(1-a)beta, where a epsilon R represents in the Argand plane (A) a straight line passsing through alpha and beta (B) a straight line passing through alpha but not through beta (C) a striaght line passing through beta but not through alpha (D) a straight line passing neighter through alpha not or through beta

If alpha and beta be the roots of the equation ax^(2)+bx+c=0 then equation whose roots are alpha+beta and alpha beta is

If alpha and beta are the roots of the equation ax^(2) + bx + c = 0 , then what is the value of the expression (alpha + 1)(beta + 1) ?

If alpha,beta are the roots of ax^(2)+bx+c=0 , alpha.beta=3 and a, b, c, are in A.P., then | alpha+beta| is

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)
