If the equation `x^(2)+2x+3=0 and ax^(2)+bx+c=0, a,b,c in R` have a common root, then `a:b:c` is

If the equations x^(2) - ax + b = 0 and x^(2) + bx - a = 0 have a common root, then

If the equation ax^(2) + bx + c = 0 and 2x^(2) + 3x + 4 = 0 have a common root, then a : b : c

If the equation x^(2)+2x+3=0 and ax^(2)+bx+c=0 have a common root then a:b:c is

If a , b , c denote the sides of a !ABC such that the equation x^(2)+sqrt2x+1=0 and ax^(2)+bx+c=0 have a common root , then C =

If the equation ax^(2)+2bx+c=0 and ax62+2cx+b=0b!=c have a common root,then (a)/(b+c)=

If ax^(2)+bx+c=0 and cx^(2)+bx+a=0 (a, b, c in R) have a common non - real root, then

If a, b, c are positive real numbers such that the equations ax^(2) + bx + c = 0 and bx^(2) + cx + a = 0 , have a common root, then
