Question

3) Fatore as expressões:

a) 15x⁷ - 3ax⁴ =
b) x⁷ + x⁸ + x⁹ =
c) a⁵ + a³ - a² =
d) 6x³ -10x² + 4x⁴ =
e) 6x²y + 12xy – 9xyz =

Answer 1

a) 15x⁷ - 3ax⁴ =

$3x^{4} \cdot(5x^{3} -a)$

b) x⁷ + x⁸ + x⁹ =

$x^{7} \cdot(x^{2} +x+1 )$

c) a⁵ + a³ - a² =

$a^{2} \cdot(a^{3}+a-1 )$

d) 6x³ -10x² + 4x⁴ =

$2x^{2} \cdot(2x^{2}+3x-5)$

e) 6x²y + 12xy – 9xyz =

$3xy\cdot(2x-3z+4)$
