Sure, here are step-by-step solutions for a sample problem: Problem: Simplify the following expression:

\frac{( x ^{2} + 3 x - 4 ) - ( x ^{2} - x - 6 )}{( x ^{2} - 4 x + 4 )}

Solution: Step 1: Simplify the numerator by removing the brackets and combining like terms:

\frac{( x ^{2} + 3 x - 4 ) - ( x ^{2} - x - 6 )}{( x ^{2} - 4 x + 4 )} = \frac{x ^{2} + 3 x - 4 - x ^{2} + x + 6}{( x - 2 ) ^{2}}

Step 2: Combine like terms in the numerator:

\frac{x ^{2} + 3 x - 4 - x ^{2} + x + 6}{( x - 2 ) ^{2}} = \frac{4 x + 2}{( x - 2 ) ^{2}}

Step 3: Factor out 2 from the numerator:

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

Step 4: Simplify the expression by cancelling out the common factor of

(x - 2)^{2}

in the numerator and denominator:

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

Therefore, the simplified expression is

\frac{2 ( 2 x + 1 )}{x - 2}
