Question

Baskara de 2x²-3x=0 urgente ...

Answer 1

Olá!!!

Resoluçao!!!

2x² - 3x = 0

a = 2, b = - 3 , c = 0

∆ = b² - 4ac
∆ = ( - 3 )² - 4 • 2 • 0
∆ = 9 - 0
∆ = 9

x = - b ± √∆ / 2a
x = - ( - 3 ) ± √9 / 2 • 2
x = 3 ± 3 / 4
x' = 3 + 3 / 4 = 6/4 : 2 = 3/2
x" = 3 - 3 / 4 = 0/4 = 0

S = { 0, 3/2 }

Espero ter ajudado,,
