If(x) =ax^4=bx^3+cx^2+dx+e(a,b,c,d,eER 0) such that f(1)+f(2) = f(2)+f(3) =f(3)+f(4)=0, then equation f(x)=0 have 1 all roots non real 2. two real and two non real roots 3 all four roots are...
Let f(1)>0 then f(2)<0 if f(2)<0 then f(3) >0 if f(3)>0 then f(4) <0 So between 1 and 2 the graph will cut x axis once similarily between 2 and 3 once and between 3 and 4...
