Thewhat is the difference between the mean and median of the first four prime numbers that are more than 4? The mean=9 and the median =11.so the ans should be -2.but in the answer sheet the ans is 0..how?

math
Mean=9 Median=11 Is it right? Then the difference between them is -2. But here in the answer sheet the ans is 0!!im really confused

If a,b,c are integers and b²=4(ac+5d²), d €N then roots of the eqn ax²+bx+c=0 are

math
Let a,b and c be real numbers such that 4a+2b+c =0 and ab>0. Then the eqn ax²+bx²+cx²=0 has-

math
Consider the eqn x²+2x-n =0 where n€N and n€[5,100]. Total no. Of different values of 'n' so that the given eqn has integral roots is-

math
If the roots of the eqn x²-2cx+ab=0 are real and unequal, then prove that the roots of x²-2(a+b)x+a²+b²+2c²=0 will be imaginary.

maths
For what values of k the expression kx²+(k+1)x+2 will be a perfect square of a linear polynomial.

math
Show that if roots of eqn (a²-bc) x²+2(b²-ac)x +c²-ab=0 are equal then either b=0 or a³+b³+c³=3abc.

maths
If a,b and c € R, then prove that the roots of the eqn 1/(x-a) + 1/(x-b) + 1/(x-c) =0 are always real and cannot have roots if a=b=c.

maths
If the roots of the eqn 1/(x+p) + 1/(x+p) = 1/r are equal in magnitude but opposite in sign, show that p+r=2r and that the product of the roots is equal to (-1/2) (p²+q²)
