To find the sum of $4x^{2}-5$ and $-2x^{2}+10$, we need to add the corresponding terms together.<br /><br />$4x^{2}-5 + (-2x^{2}+10)$<br /><br />Combine like terms:<br /><br />$4x^{2} - 2x^{2} - 5 + 10$<br /><br />Simplify:<br /><br />$2x^{2} + 5$<br /><br />Therefore, the correct answer is $2x^{2}+5$.
