Question

${x}^{2} - 31x = 0$
formula de bhaskara

Answer 1

Olá!!!

Resolução!!!

x² - 31x = 0,

a = 1, b = - 31, c = 0

∆ = b² - 4ac
∆ = ( - 31 )² - 4 • 1 • 0
∆ = 961 - 0
∆ = 961

Bhaskara :

x = - b ± √∆ / 2a
x = - ( - 31 ) ± √961 / 2 • 1
x = 31 ± 31 / 2
x' = 31 + 31 / 2 = 62/2 = 31
x" = 31 - 31 / 2 = 0/2 = 0

S = { 0, 31 }

Espero ter ajudado!!!
