Question

5x elevado a 2 -x=0​

Answer 1

5x² - x = 0

x • (5x - 1) = 0

x= 0

5x - 1 = 0

5x = 0 + 1

5x= 1

x= 1/5

S= ( 1/5 , 0)

Answer 2

Resposta:

$\text{S} = \{0,\:\frac{1}{5}\}$

Explicação passo-a-passo:

$5 {x}^{2} - x = 0 \\ x\cdot(5x - 1) = 0 \\ \\ \bf{x = 0} \\ \\ 5x - 1 = 0 \\ 5x = 0 + 1 \\ 5x = 1 \\ \bf{x = \frac{1}{5} }$
