Question

3) A equação x ∙ (x – 1) = 132 na forma reduzida é:
A) x 2 – x – 132 = 0
B) x 2 – x – 130 = 0
C) x 2 – x – 122 = 0
D) x 2 – x – 120 = 0

Answer 1

Oie, tudo bom?

Resposta: a) x² - x - 132 = 0.

$x \: . \: (x - 1) = 132$

$x \: . \: x - x = 132$

$x {}^{2} - x = 132$

$\boxed{x {}^{2} - x - 132 = 0 }$
