Question

Simplifique as expressões algébricas

(x-2)2 + a(3a+2)



(m+1) (m-1) + (m+1) - 2m

Answer 1

Simplifique as expressões algébricas :

a)
(x-2)^2 + a(3a+2)=>

=>x^2 -4x+ 4 + 3a^2 + 2a

b)

(m+1) (m-1) + (m+1) - 2m=>

=> ( m - 1 + 1 )*( m + 1 ) - 2m=>

=>m * ( m + 1 ) - 2m=>

=> m *( m + 1 - 2 )=>

=> m ( m -1 )
