Question

calcule as equações de grau

a- X²–5×+6=0​

Answer 1

Resposta:

x =2,x =3

1 , 2

Explicação passo-a-passo:

x^2 -5x+6=0

x^2 -5x+6=0

x^2 -2x-3x+6=0

x×(x-2)-3x+6=0

x^2 -2x+6=0

x×(x-2)-3(x-2)=0

(x-2)×(x-3)=0

x-2=0

x-3=0

x-2=0

x-2+2=0+2

x=0+2

x-2+2=0+2

x=2

x-2=0

x-3=0

x=2

x-3=0

x-3+3=0+3

x=0+3

x-3+3=0+3

x=3

x-2=0

x-3=0

x=2

x=3

x =2, x =3

1 2

Resposta

x =2, x =3
