If `16x^4-32x^3+ax^2+bx+1=0`, `a,b in R` has positive real roots only, then `a-b` is equal to :

If 16 x^(4) -32x ^(3) + ax ^(2) +bx + 1=0, a,b,in R has positive real roots only, then |b-a| is equal to :

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^(2)+ax+b=0 and x^(2)+bx+a=0,(a ne b) have a common root, then a+b is equal to

If x^(2)+ax+b=0 and x^(2)+bx+a=0,(a ne b) have a common root, then a+b is equal to
