For what values of x is the rational expression below undefined?

Mathematics
1 answer:
WINSTONCH [101]4 years ago
7 0

Answer: The rational expression below is undefined when x is equal +5 and -5.

Step-by-step explanation: The rational expression will be undefined when the denominator is equal to zero. So, first you have to take the denominator and make it equal to zero.

3x^{2} -75=0\\

Then you divide the whole thing by three to get this:

x^{2} -25=0

Now you move 25 over to the other side of the equation and take the square-root of both sides.

x^{2} =25\\x= +/- \sqrt{25}

Since the square root of 25 is equal to five. We know that the rational expression will be undefined when x= -5 and +5

Answer:

When you are typing your question, on the bottom, there should be icons for bold, italic, and underline. The very last one is a paperclip looking icon. If you click on the paperclip, it will ask you to add a photo. If you're using a laptop/computer, then you need to save your picture in your files. Then just click on the picture you want to add.

What value(s) of x will make each equation below true
Dahasolnce [82]

We need to solve for x. Let's try problem b:

2x-6=3x+1-x-7

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

2x-6=2x-6

Since this is true, your answer would be:

All real numbers

------------------------------------------------------------------

Let's solve for problem c:

3x+1=43

Let's isolate x, so subtract 1 from both sides:

3x=42

Since x can't have a coefficient, divide both sides by 3:

\frac{3x}{3}=\frac{42}{3}

x=14

So, only the value of 14 would make this equation true.

------------------------------------------------------------------

Let's try problem d:

4x-1=4x+7

Let's get our whole numbers on the right side. Add 1 to both sides:

4x=4x+8

Subtract 4x from the right side on both sides:

0=8

Since this is not true, your answer would be:

No solution
