[" The expression "(x^(2)+2x+1)/(x^(2)+2x+7)" lies in the "],[" intweral i "(x in R)-]

The expression (x^(2)+2x+1)/(x^(2)+2x+7) lies in the interval; (x in R)

the expression x^2 -5x-6 is negative is x lies in

Given that for all real x, the expression (x^(2)-2x+4)/(x^(2)+2x+4) lies between (1)/(3) and 3 the values between which the expression (9tan^(2)x+6tanx+4)/(9tan^(2)x-6tanx+4) lies are

The expression ((x-1)(x-2)(x^(2) - 9x + 14))/((x-7)(x^(2) - 3x + 2)) in the lowest terms is:

If x is real and 5x^(2)+2x+9>3x^(2)+10x+7, then x lies in the interval

the expression -7x ^2 + 8x -9 is positive if x lies in
