can someone please help me with this Rational Expression?

Answer 1

here it is

Answer 2

Sure, do you want to simplify it I suppose? Well, let's consider what you might do to simplify these fractions:

1/2 + 1/4

Since you know 1/2 is just 2/4 you can see that you're really just multiplying 1/2 by a fancy version of 1, which is 2/2. All you need to do now is multiply both fractions by something until their denominators both have the same things in common.

I'll help you along, show me your best guess.

Answer 3

typo there, first line should have been
\[\frac{x+1}{x^2}=\frac{4(x+1)}{4x^2}\]

Answer 4

Lack of edit button sucks.

Answer 5

\[\frac{3}{4x}=\frac{3x}{4x^2}\]
\[\frac{4(x+1)}{4x^2}+\frac{3x}{4x^2}=\frac{4(x+1)+3x}{4x^2}\]
\[=\frac{4x+4+3x}{4x^2}=\frac{7x+4}{4x^2}\]
