Question

Simplify the expression: 4/(5x) - 3/x

Answer 1

You have to set the denominators equal, so I multiplied x and 3 by 5. Now, you have
4/5x - 15/5x. Subtract the numerators, and keep the denominator 5x. So your final answer will be -11/5x. Hope I helped :)

Answer 2

thank you so much(: 3/x+2/x^2 is 5/x the simplified form?

Answer 3

Are you asking if 5/x is the simplified form of 3/x + 2/x^2? If you are, then that would be incorrect because the denominators are not the same. To make them the same, you would square the 3/x. So that makes 9/x^2 + 2/x^2. Just add the numerators and keep the denominator x^2. So the answer is 11/x^2.

Answer 4

why did you square 3/x. would you not just multiply 3*x and x*x to get 3x/x^2+2/x^2 or am i wrong

Answer 5

Ooops I made a mistake haha. Well that's just embarrasing. But yes, you would multiply 3 and x both by x. So what you just did is correct. lol.

Answer 6

haha oh well thank you so much(: great

Answer 7

great help*

Answer 8

no problem:)
