Question

estão 5) Efetue a divisão dos polinomios pelos monômios abaixo: a) (x - 3x - x + 6) : (x)
b) (9x² +21x - 12 x ): (3x)​

Answer 1

Resposta:

$a)(x-3x-x+6):(x)\\\\=(-2x-x+6):(x)\\\\=(-3x+6):(x)\\\\=(-3x+6) \ . \ \frac{1}{x} \\\\=\frac{-3+6x}{x}$

$b) (9x^2+21x-12x):(3x)\\\\=\frac{9x^2+9x}{3x} \\\\=\frac{9x(x+1)}{3x} \\\\=\frac{9(x+1)}{3} \\\\=3(x+1)$
