" If "x^(2)+bx+c=0&2x^(2)+9x+10=0" have both roots common then find "b&c

The equations ax^(2) + bx+ c =0, x^(3) -2x^(2) +2x -1 =0 have tow roots common, then find the value of a+b.

If the equations ax^(2)+bx+C=0 and x^(2)+2x+4=0 have a common root then find a:b:c

If x^(2)+bx+c=0,x^(2)+cx+b=0(b!=c) have a common root then b+c=

If x^2+mx+1 =0 and (b-c) x^2+(c-a)x+(a-b) =0 have both roots common,then

If x^(2)+mx+1=0 and (b-c)x^(2)+(c-a)x+(a-b)=0 have both roots common,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 ax^(2) + bx + c = 0 and 2x^(2) + 3x + 4 = 0 have a common root, then a : b : c

If a,b,c in R and the equation ax^(2)+bx+c=0 and x^(2)+x+1=0 have a common root,then

If a,b,c, in R and equations ax^(2) + bx + c =0 and x^(2) + 2x + 9 = 0 have a common root then
