" 4.For "x in R," prove that the given expression "(x^(2)+34x-71)/(x^(2)+2x-7)" cannot lie between "5" and "9

For x in R, Prove that the given expression (x^2+34x-71)/(x^2+2x-7) can not lie between 5 and 9.

If x is real show that the expressions (x^2+34x-71)/(x^2+2x-7) has no value between 5 and 9.

factorize the given expression 2x^2-7x-15

If x is real , then the expression (x^(2) + 34x - 71)/(x^(2) + 2x - 7 ) can have no value between :

Find the range of f(x)=(x^(2)+34x-71)/(x^(2)+2x-7)

fx be real,prove that the value of (2x^(2)-2x+4)/(x^(2)-4x+3) cannot lie between -7 and 1

If x be real, prove that the value of (2x^(2)-2x+4)/(x^(2)-4x+3) cannot lie between -7 and 1.

If x be real, prove that the value of (11x^(2)+12x+6)/(x^(2)+4x+2) cannot lie between -5 and 3.

If x is real, prove that the value of the expression ((x-1)(x+3))/((x-2)(x+4) cannot be between 4/9 and 1.

If x is real, prove that the value of the expression ((x-1)(x+3))/((x-2)(x+4)) cannot be between (4)/(9) and 1.
