Question

Resolva a equaçao x²-5x+6=0

Answer 1

Oi... Barbosa125

Δ = b2 - 4.a.c
Δ = -52 - 4 . 1 . 6
Δ = 25 - 4. 1 . 6
Δ = 1Há 2 raízes reais.

2) Aplicando Bhaskara:

x = ( -b +- √Δ)/2a

x' = (-5 + √1)/2.1

x' = 6 / 2

x' = 3

x'' = (-5 - √1)/2.1

x'' = 4 / 2

x'' = 2

Bons estudos

Answer 2

= b^2 - 4ac
= (-5)^2 - 4. 1. 6
= 25 - 24
= 1

X = -b +- (raiz de )/2a
X = 5 +- 1/ 2


X'= 5 + 1/ 2
X'= 6/2
X'= 3


X"= 5 - 1/2
X"= 4/2
X"= 2
