Question

Simplifique a expressão algébrica:
x²-10x+25/5x²-26x+5

Answer 1

$= \frac{x {}^{2} - 10x + 25}{5x {}^{2} - 26x + 5 }$

$= \frac{(x - 5) {}^{2} }{5x {}^{2} - x - 25x + 5 }$

$= \frac{(x - 5) {}^{2} }{x \: . \: (5x - 1) - 5(5x - 1)}$

$= \frac{(x - 5) {}^{2} }{(5x - 1) \: . \: (x - 5)}$

$\boxed{ = \frac{x - 5}{5x - 1} }$
