Which expression is equivalent to the following complex fraction? X+5/x+2-x+1/x^2+2x
ICE Princess25 [194]

Answer:

Final answer will be the choice which matches best with expression

\frac{x^2+4x-1}{x\left(x+2\right)} or

\frac{x^2+4x-1}{x^2+2x}


Step-by-step explanation:

Given expression is:

\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{\left(x^2+2x\right)}

We begin by factoring denominators:

=\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}

Multiply and divide first term by (x) to make denominators equal.

=\frac{x\left(x+5\right)}{x\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}

Since denominators are equal so we can combine numerators.

=\frac{x\left(x+5\right)-\left(x+1\right)}{x\left(x+2\right)}

Now simplify

=\frac{x^2+5x-x-1}{x\left(x+2\right)}


=\frac{x^2+4x-1}{x\left(x+2\right)}


=\frac{x^2+4x-1}{x^2+2x}

Hence final answer will be the choice which matches best with expression

\frac{x^2+4x-1}{x\left(x+2\right)} or

\frac{x^2+4x-1}{x^2+2x}
