Question

3/x+1 + 4x/x-2
Explain please?

Answer 1

can you rtype this? it doesn't make since

Answer 2

explain what? it's an expression involving a fractions of polynomials?

Answer 3

\[\frac{ 4x }{ x-2 }+\frac{ 3 }{ x+1 }\]
How am I supposed to do it??

Answer 4

well to add fractions of polynomials they must have the same divisor. So if you have:

a/b+c/d you do ad/bd+bc/bd=(ad+bc)/bd, that is assuming the polynomials b and have no common factors. so in your case you have
(4x(x+1)+3(x-2))/((x-2)(x+1)
