If the equation `2x^2 + 3x+51 = 0` and `x^2 + 2x + 3 lambda = 0` have a common root then `lambda` is equal to:(a) 0 (b) -1 (C) 0, -1 (d) 2,-1:

If x^(2)+x-1=0 and 2x^(2)-x+lambda=0 have a common root then

If the equations x^(2) + 2x + 3 lambda =0 and 2x^(2) + 3x + 5 lambda = 0 have a non- zero common roots. then lambda = (a)1 (b)-1 (c)3 (d)None of these

If the equations x^2+2x+3lambda=0 and 2x^2+3x+5lambda=0 have a non-zero common roots, then lambda= (a) 1 (b) -1 (c) 3 (d) none of these

If the equations x^(2)+bx-1=0 and x^(2)+x+b=0 have a common root different from -1 then |b| is equal to

If the equation x^(2)+bx-1=0 and x^(2)+x+b=0 have a common root different from -1 then |b| is equal to

If the equations x^2+bx-1=0 and x^2+x+b=0 have a common root different from -1 then |b| is equal to

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 equations x^(2)+2x+3 lambda=0 and 2x^(2)+3x+5 lambda=0 have a non-zero common roots,then lambda=1 (b) -1( c) 3( d) none of these

If x^(2)+3x+3=0 and ax^(2)+bx+1=0 ,a,b in Q have a common root,then value of (3a +b) is equal to : (A) (1)/(3) (B) 1 (C) 2 (D) 4

If x^(3)+ax+1=0 and x^(2)+ax+1=0 have a common roots then the value of |a| can be equal to
