Question

x2+ 2x = 0
*O x2 e x elevado a 2*

Answer 1

x² + 2x = 0

∆= b² - 4ac

∆= 2² - 4 (1)(0)

∆= 4-0

∆= 4

x= -b ± √∆ / 2

x= -2 ± √4 / 2

x= -2 ± 2 / 2

x'= -2 + 2 / 2

x'= 0 / 2

x'= 0

x"= -2 -2 / 2

x"= -4 / 2

x"= -2

Resposta:

x'= 0

x"= -2

Bons Estudos!

Answer 2

Resposta:

V = {0, 2}

Explicação passo-a-passo:

X^2+ 2x = 0

x.(x-2) = 0

x = 0

x - 2 = 0

X = 2

R.: v = { 0,2}
