Question

Factor: 16w3 – u4w3​

Answer 1

ANSWER✔

$\sf\dashrightarrow -u^4w^3+16w^3$

$\sf\implies 16w^3-u^4w^3$

$\sf\implies w^3(16-u^4)$

$\sf\implies w^3(4^2-(u)^4$

$\sf\implies w^3((2^2)^2-(u^2)^2$

$\sf\implies w^3(u^2+4)(u+2)(-u+2)$

$\large{\boxed{\bf{ \star\:\: w^3(u^2+4)(u+2)(-u+2)\:\: \star}}}$

Answer 2

Answer:

16w3 – u4w3.

= w3(16 – u4).

= w3(42 - ((u2)2).

= w3(4 + u2)(4 - u2).

= w3(4 + u2)(22 - u2).

= w3(4 + u2)(2 + u)(2 - u).
