Question

Resolva as equações: (A) x + 1 + x² = 0 (B) 3m - 2m² = 0

Answer 1

A )x+1+x^2=0》x^2+x+1=0》a=1,b=1,c=1》x=-1+,-\/1^2-4(1)(1)/2(1)》x=-1+,-\/1-4/2》x=-1+,-\/-5/2》x=-1+,-E/2 ( E= nao existe porque e negativo em rsiz nunca existe... B)3m-2m^2=0》m(3-2m)=0》m1=0 , 3-2m=0》m1=0 , 3= 2m2=0》m1=0 , 3/2=m2
