Question

Resolva as equações incompletas do segundo grau

a)5x² - x =0
b)2x² - 2 = 0
c)5x² = 0

Answer 1

a) 5x² - x = 0 → x × (5x - 1) = 0 x = 0

5x - 1 = 0 → 5x = 1 → x = 1

5

b) 2x² - 2 = 0 → 2x² = 2 → x² = 2 → x² = 1 →

2

x = √1 → x = 1

c) 5x² = 0 → x² = 0 → x² = 0 → x = √0 →

5

x = 0

Espero ter ajudado!!!

Answer 2

Resposta:

Explicação passo-a-passo:

a) 5x² - x = 0 → x × (5x - 1) = 0 x = 0

5x - 1 = 0 → 5x = 1 → x = 1

5

b) 2x² - 2 = 0 → 2x² = 2 → x² = 2 → x² = 1 →

2

x = √1 → x = 1

c) 5x² = 0 → x² = 0 → x² = 0 → x = √0 →

5

x = 0
