Question

Alguém calcula essas Fatoração?
m^ 7-n^3
A^3+a^6
X^2+13x
5m^3-m^2
X^50+x
8x^6-12x^3
15x^3-21x^2

Answer 1

tO NO 7° série ainda...HAUHSUHFHOSUHOHO.... desculpa... aff's

Answer 2

a)
$m^{7} - m^{3} = m^{3} ( m^{4} -1)= m^{3} ( m^{2} +1)( m^{2} -1)=$

=$m^{3}( m^{2} +1)(m+1)(m-1)$

b)
$a^{3} + a^{6} = a^{3} (1+ a^{3} )$

c)
$x^{2} +13x=x(x+13)$

d)
$5 m^{3} - m^{2} = m^{2} (5m-1)$

e)
$x^{50} +x=x( x^{49} +1)$

f)
$15 x^{3} -21 x^{2} =3 x^{2} (5x-7)$
