Question

Fatore, colocando em evidência os fatores comuns.

a) $x^{2} + x=$

b) $x^{4} - x^{2} +x=$

c) $3 a^{3} +12 a^{7} =$

d) $15y^{5} - 10 y^{3} + 25 y^{2} =$

e) $a^{3} x^{3} + 4 a^{2} x^{2} y$

Answer 1

a) x+x² = x(1+x)

b) $x^{4} -x^{2} +x=x(x^{3} -x+1)$

c)$3a^{2} +12a^{7} =3a(a+4a^{6} )$

d)$15y ^{5} -10y^{3} +25y^{2} =5y(3y^{4} -2y^{2} +5y)$

e)$ax(a^{2} x^{2} +4axy)$
