Factorise a.x3+4.a.x​
Contact [7]

Answer:

{ax}^{3}  + 4ax \\

factorise out a and x :

{ \boxed{answer{= ax( {x}^{2}  + 4) }}}\\ but \: farther \: more :  \\  = ax( {x}^{2}  +  {2}^{2} )

but from general factorization:

{ \boxed{( {a}^{2} +  {b}^{2}) =  {(a + b)}^{2}   - 2ab }}

a » x

b » 2

therefore:

= ax \{ {(x + 2)}^{2}  - 2(x)(2) \} \\  \\  = { \boxed{ \boxed{ax( {x + 2)}^{2} - 4x }}}
