Consider the equation ; x 4 + ax 3 - 6x 2 + ax + 1 find parameter of a for which equation has two distict positive roots ?
 
 
Its not properly uploaded in previous comment. The answer is a is (-infinity,2). Consider only positive side of x-axis for analysis, that is x>0. At a=2, you get f(x)=x 4 +2x 3 -6x 2 +2x+1, ...

When a(is less than)2, {f(x) when a(is less than)2} (is less than) {f(x) when a=2}. At x=1, you will get f(x)(is less than)0. As f(0)(is less than)0 and f(infinity)>0 , you will get two...

I am little bit confused in a question that "If there are two Children in a family then probability that both are boys" What Should be its Ans can anyone please explain
 
 
I am Sorry above one is incorrect.. The right one is Here, Sample Space = {B-B, B-G, G-B, G-G} so, n(s)=4 Events having both boys= {B-B} so, n(E)= 1 Thus, P E = n(E)/n(S) P E = 1/4 Ans....

How to find root of 8+3i in complex numbers???????????????????????
 
 
Let x+iy=root of 8+3i (x+iy) 2 =8+3i x 2 -y 2 +2xyi=8+3i On comparing, x2-y2=8 and 2xy=3 ie x=3/(2y) 9/(4y 2 ) – y 2 =8 Solve and get the values of x and y z=x+iy
