Question

resolva a equacao de 2°grau 2ײ+×-3​

Answer 1

Resposta:

Explicação passo a passo:

2ײ+×-3 = 0

a = 2 ; b = 1; c = - 3

Δ = b² - 4ac

Δ = 1² - 4.2.(-3)

Δ = 1 + 24

Δ = 25

x = ( - b +/- √Δ)/2a

x = ( - 1 +/- √25)/2.2

x = (-1 +/ - 5)/4

x' = (-1-5)/4 = -6/4 = - 3/2

x" = (-1+5)/4 = 4/4 = 1
