Simplify the following rational expression. X^2- 16x +64
———————
4x^2 -36x+32
Which values of I make the expression undefined?

9514 1404 393

  (x-8)/(4x-4)  x ≠ 1 or 8

Step-by-step explanation:

Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.

The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.

36÷48=0.75

0.75=

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
