To subtract the expression $10x^2 + 3$ from $9x^2 + 4x + 1$, you perform the subtraction as follows:

$(9x^2 + 4x + 1) - (10x^2 + 3)$

Distribute the negative sign across the second expression:

$9x^2 + 4x + 1 - 10x^2 - 3$

Now, combine like terms:

• Combine the $x^2$ terms: $9x^2 - 10x^2 = -x^2$
• The $x$ term remains: $4x$
• Combine the constant terms: $1 - 3 = -2$

So, the result is:

$-x^2 + 4x - 2$
