Question

Calcule 2x^2-32x=0 (com formula de baskara) E PARA AMNH PFRV

Answer 1

2x^2-32x=0

a = 2 b = -32 c = 0

▲ = b^ 2 - 4. a. c
▲ = (-32)^2 - 4 . 2 . 0
▲ = 1024 - 0
▲ = 1024

x = - b + - (raiz de delta) / 2 . a
x = -(-32)+ - (1024) / 2 . 2
x = 32 +- 32 / 4
x1 = 32 + 32 / 4
x1 = 64 / 4 = 16

x2 = 32 - 32 / 4
x2 = 0 / 4 = 0

S = { 16 , 0 }
