Question

efetue as divisões seguintes fatorando o dividendo letra c e d

Answer 1

$c) \\ \frac{25x^{2} - 10x + 1}{(5x - 1)^{2} } = \\ \frac{25x^{2} - 10x + 1}{(5x - 1).(5x - 1)} = \\ \frac{(5x - 1)^{2}}{(5x - 1).(5x - 1)} = \\ \frac{(5x - 1).(5x - 1)}{(5x - 1).(5x - 1)} = 1$
$d)\\ \frac{ {x}^{2} + 6x + 9 }{x + 3} = \\ \frac{(x + 3)^{2}}{(x + 3)} = \frac{(x + 3).(x + 3)}{(x + 3)} = x + 3$

Answer 2

Vamos lá

c) (25x² - 10x + 1)/(5x - 1)²

(25x² - 10x + 1)/(25x² - 10x + 1) = 1

d)

(x² + 6x + 9)/(x + 3) = (x + 3)*(x + 3)/(x + 3) = x + 3
