me ajude por favor

Answer 1

a) (3a-1)^2 = 9a^2 -6a +1

b)(3m-5n)^2=3m^2-30mn+25n

c)4x^2-12x^2+9x^2
d)a^4-ab^5+b6
e)9x^4-3x^3.y^2
f)(5a-1)^2=25a^2-10a+1
g)(ab^2-a^2b^2)^2=ab^4-2.(-a).ab^4 . 2.b.ab^4
j)(x/3-y)^2=x^2/9-2.y/3 +y

Answer 2

Resposta:

Explicação passo-a-passo:

a) (3a-1)^2 = 9a^2 -6a +1

b)(3m-5n)^2=3m^2-30mn+25n

c)4x^2-12x^2+9x^2

d)a^4-ab^5+b6

e)9x^4-3x^3.y^2

f)(5a-1)^2=25a^2-10a+1

g)(ab^2-a^2b^2)^2=ab^4-2.(-a).ab^4 . 2.b.ab^4

j)(x/3-y)^2=x^2/9-2.y/3 +y
