" 4.Show that if "x" is real,the expression "(x^(2)-bc)/(2x-b-c)" has no value between "b" and "c.

IF x is real , then ( x^2 - bc ) /( 2x -b-c) has _____ values between b and c

If x is real , show that the expressions (x^2-ab)/(2x-a-b) has no real value between a and b.

If x in R and b

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

If x is real show that the expressions (3x-5)/(x^2-1) has no value between 1/2 and 9/2 .

If x be real and 0

If x is real show that the expressions ((x-1)(x+3))/((x-2)(x+4)) has no value between 4/9 and 1.

If x is real then the expressions (x^2+2x-11)/(x-3) assumes those values which do not lie between a and b , find a and b.

For x in R, the expression (x^(2)+2x+c)/(x^(2)+4x+3c) can take all real values if c in
