I don’t understand how to solve it and in what sequence?

[math]\frac{ \sqrt{4+3x-x^{2}}+x-4 }{ \log_{x}({2x-4})^{2} } \geqslant 0[/math]

My initial thought is to consider two cases. One when the denominator is +ve, and one when it's -ve. What must the numerator be in each case?

Please show some work so that we know where you need help...
 
In addition to the questions asked by cubist, what can we deduce about x from [MATH]log_x[/MATH]?

How about what can be deduced from [MATH]\sqrt{4 + 3x - x^2}[/MATH]?
 
Draw a number line and mark the regions where the top line is positive or negative (by first finding where it =0). Also restrict this to the values of x for which the top line exists.

Draw a number line and mark the regions where the bottom line is positive or negative (by first finding where it =0). Also restrict this to the values of x for which the bottom line exists.
(Note [MATH]\log_x (2x-4)^2=0[/MATH] means [MATH](2x-4)^2=1[/MATH])

Use these to find the regions where they both have the same sign (and exist and the fraction itself exists).
