If the equation `x^2+b x-a=0"and" x^2-a x+b=0` have a common root, then a.`a+b=0` b. `a=b` c. `a-b=1` d. `a+b=1`

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

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

If the equations a x^2+b x+c=0 and x^3+3x^2+3x+2=0 have two common roots, then a) a=b=c b) a=b!=c c) a=-b=c d) a+b+c=3

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