Yes,
x^2 -4x+4
= x^2 -2x-2x +4
= x (x-2) -2 (x-2)
= (x-2)(x-2)

As you can see it has repeated factor.

What is the difference?
Whitepunk [10]

Answer:

\frac{x^2+3x  -12}{(x-5) (x +3)(x+7)}

Step-by-step explanation:

Given

\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}

Required

Calculate the difference

We start by factorizing the denominator of both fractions

\frac{x}{x^2-2x-15} - \frac{4}{x^2+2x-35}

\frac{x}{x^2+3x - 5x -15} - \frac{4}{x^2+7x - 5x-35}

\frac{x}{x(x+3) - 5(x +3)} - \frac{4}{x(x+7) - 5(x+7)}

\frac{x}{(x-5) (x +3)} - \frac{4}{(x-5)(x+7)}

Take LCM

\frac{x(x+7) - 4(x +3)}{(x-5) (x +3)(x+7)}

Open Brackets

\frac{x^2+7x - 4x -12}{(x-5) (x +3)(x+7)}

\frac{x^2+3x  -12}{(x-5) (x +3)(x+7)}

This can't be simplified any further;
