Question

qual e o valor de ײ-3×-4=0

Answer 1

Resposta:

× = - 1 e 4

Explicação passo a passo:

ײ-3×-4=0

× = (-b ± √(b² - 4 • a • c)) / (2 • a)

× = (-(-3) ± √((-3)² - 4 • 1 • (-4))) / (2 • 1)

× = (3 ± √(9 - (-16))) / 2

× = (3 ± √(9 + 16)) / 2

× = (3 ± √25) / 2

× = (3 ± √5²) / 2

× = (3 ± 5) / 2

×₁ = (3 - 5) / 2

×₁ = (- 2) / 2

×₁ = (- 1)

×₂ = (3 + 5) / 2

×₂ = 8 / 2

×₂ = 4
