If` c^2 = 4d` and the two equations `x^2-ax + b= 0` and `x^2-cx + d=0` have a common root, then the value of `2(b + d)` is equal to 0, have one

Ifc^(2)=4d and the two equations x^(2)-ax+b=0 and x^(2)-cx+d=0 have a common root,then the value of 2(b+d) is equal to 0 ,have one

If c^(2)=4d and the two equations x^(2)-ax+b=0 and x^(2)-cx+d=0 have one common root. then the value of 2(b+d) ) is equal to (A)? 13 ) ac (C) 2ac(D) ane

If the equations x^(2) + ax+1=0 and x^(2)-x-a=0 have a real common root b, then the value of b is equal to

If the equation x^2+ax+bc=0" and " x^2-bx+ca=0 have a common root, then a+b+c =

For a ne b, if the equation x ^(2) + ax + b =0 and x ^(2) + bx + a =0 have a common root, then the value of a + b equals to:

If the equation x^2+ax+bc=0" and " x^2+bx+ca=0 have a common root, then a+b+c =

If the equations ax^2 + bx + c = 0 and x^3 + x - 2 = 0 have two common roots then show that 2a = 2b = c .

If the equations x^2+ax+b=0 and x^2+bx+a=0 have one common root. Then find the numerical value of a+b.
