\frac{x+3}{x+3}-\frac{2x-2}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{x+3}{x+3}.
\frac{x+3-\left(2x-2\right)}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
Since \frac{x+3}{x+3} and \frac{2x-2}{x+3} have the same denominator, subtract them by subtracting their numerators.
\frac{x+3-2x+2}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
Do the multiplications in x+3-\left(2x-2\right).
\frac{-x+5}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
Combine like terms in x+3-2x+2.
\frac{\left(-x+5\right)\left(x+3\right)}{\left(x+3\right)^{2}}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x+3 and \left(x+3\right)^{2} is \left(x+3\right)^{2}. Multiply \frac{-x+5}{x+3} times \frac{x+3}{x+3}.
\frac{\left(-x+5\right)\left(x+3\right)+x^{2}-2x+1}{\left(x+3\right)^{2}}
Since \frac{\left(-x+5\right)\left(x+3\right)}{\left(x+3\right)^{2}} and \frac{x^{2}-2x+1}{\left(x+3\right)^{2}} have the same denominator, add them by adding their numerators.
\frac{-x^{2}-3x+5x+15+x^{2}-2x+1}{\left(x+3\right)^{2}}
Do the multiplications in \left(-x+5\right)\left(x+3\right)+x^{2}-2x+1.
\frac{16}{\left(x+3\right)^{2}}
Combine like terms in -x^{2}-3x+5x+15+x^{2}-2x+1.
\frac{16}{x^{2}+6x+9}
Expand \left(x+3\right)^{2}.

Since \frac{x+3}{x+3} and \frac{2x-2}{x+3} have the same denominator, subtract them by subtracting their numerators.
\frac{x+3-2x+2}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
Do the multiplications in x+3-\left(2x-2\right).
\frac{-x+5}{x+3}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
Combine like terms in x+3-2x+2.
\frac{\left(-x+5\right)\left(x+3\right)}{\left(x+3\right)^{2}}+\frac{x^{2}-2x+1}{\left(x+3\right)^{2}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x+3 and \left(x+3\right)^{2} is \left(x+3\right)^{2}. Multiply \frac{-x+5}{x+3} times \frac{x+3}{x+3}.
\frac{\left(-x+5\right)\left(x+3\right)+x^{2}-2x+1}{\left(x+3\right)^{2}}
Since \frac{\left(-x+5\right)\left(x+3\right)}{\left(x+3\right)^{2}} and \frac{x^{2}-2x+1}{\left(x+3\right)^{2}} have the same denominator, add them by adding their numerators.
