this is all. hope that it is helpful

Answer 2

Answer:

$16x^{5} - 144x^{3}=16x^{3}(x+3)(x-3)$

Step-by-step explanation:

$16x^{5} - 144x^{3}\\=16x^{3}\times x^{2}-16x^{3}\times 9\\=16x^{3}(x^{2} - 9)\\=16x^{3}(x^{2} - 3^{2})$

/* By algebraic identity :

a² - b² = ( a + b )( a - b ) */

$= 16x^{3}(x+3)(x-3)$

Therefore.,

$16x^{5} - 144x^{3}=16x^{3}(x+3)(x-3)$
