Question

11 x ao quadrado menos x igual a zero

Answer 1

$11x^2 - x = 0\\x(11x - 1) = 0\\\cfrac{x(11x - 1)}{x} = \cfrac{0}{x} \\\\11x - 1 = 0\\11x = 1\\x = \cfrac{1}{11}$

x = 1/11

Explicação passo-a-passo:

11x² - x = 0

a= 11 b= -1 c=0

∆= b² - 4 . a . c

∆= (-1) ² - 4 . 11 . 0

∆= 1 - 0

∆= 1

x= -b ± ✓∆

2 . a

x= -( -1 ) ± ✓0
