Question

Qual deve ser o valor de m para que a equação mx²-3x+6=0 seja do 2° grau?
​

Answer 1

Resposta:

mx2- 3 x + 6 = 0

( m ) ⋅x2+ ( - 3 ) ⋅ x + ( 6 ) = 0

x =- ( - 3 ) ±( - 3 )2- 4 ⋅ ( m ) ⋅ ( 6 )-----------------√2 ⋅ ( m ), m ≠ 0

x =3 ±9 - ( 24 m )--------√2 m

x =3 ±- 24 m + 9---------√2 m

x1=3 +- 24 m + 9---------√2 m

x2=3 -- 24 m + 9---------√2 m
