Question

Resolva a equação x² - 16x = 0

Answer 1

Resposta ↓

Conjunto solução : s = {16, 0}

Explicação passo-a-passo:

Utilizarei a fórmula de bháskara :

x² - 16x = 0

Coeficientes :

• a = 1
• b = - 16
• c = 0

Δ = b² - 4.a.c

Δ = (-16)² - 4 . 1 . 0

Δ = 256

$x = \cfrac{-b\pm\sqrt{\Delta} }{2.a} \\\\\\x = \cfrac{16\pm16}{2} \\\\\\x' = \cfrac{32}{2} \\\\\\x' = 16\\\\\\x" = \cfrac{0}{2} \\\\\\x" = 0$
