​

Answer 1

Answer:

use identity of (a-b)3

Answer 2

SoluTion:-

$→\;\sf{ {(5 - x)}^{3}}$

• $\boxed{\pink{\sf{(a-b)³ = a³-3a²b+3ab²-b³}}}$

$→\;\sf{{5}^{3} - 3 \times {5}^{2}x + 3 \times 5 {x}^{2} - {x}^{3}}$

$→\;{\sf{125 - 75x + 15 {x}^{2} - {x}^{3} }}$

$→\;\green{\bf{{x}^{3} - 15 {x}^{2} + 75x - 125}}$
