Solution

Given: subtract $3 x (x - 4 y + 5 z)$ from $4 x (2 x - 3 y + 10 z)$
$= 4 x (2 x - 3 y + 10 z) - (3 x) (x - 4 y + 5 z)$
$= (8 x^{2} - 12 x y + 40 x z) - (3 x^{2} - 12 x y + 15 x z)$
$= (8 x^{2} - 3 x^{2}) + (- 12 x y + 12 x y) + (40 x z - 15 x z)$
$= 5 x^{2} + 25 x z$
$= 5 x (x + 5 z)$
Therefore, the value of the given expression is $5 x (x + 5 z)$
