The minimum value of (x-a)(x-b) is

The minimum value of 2x^2 +x-1 is

The minimum value of x^(x) is attained when x is equal to

The minimum value of (x)/( log x) is

The minimum value of 9^x+9^(1-x),x inR, is

The minimum value of (x^2+(250)/x) is (a) 75 (b) 50 (c) 25 (d) 55

The minimum value of 3^(x)+3^(1-x), x in R

x_(1) and x_(2) are two positive value of x for which 2 cos x,|cos x| and 3 sin^(2) x-2 are in GP. The minimum value of |x_(1)-x_(2)| is equal to

If the minimum value of x^2+2x+3 is m and maximum value of -x^2+4x+6 is M then m+M=
