To simplify the expression $(-6x^{2}+x-6)-(4x^{2}-6x-4)$, we need to distribute the negative sign to each term in the second parentheses and then combine like terms.<br /><br />Step 1: Distribute the negative sign to each term in the second parentheses.<br />$(-6x^{2}+x-6)-(4x^{2}-6x-4) = -6x^{2}+x-6-4x^{2}+6x+4$<br /><br />Step 2: Combine like terms.<br />$-6x^{2}+x-6-4x^{2}+6x+4 = (-6x^{2}-4x^{2})+(x+6x)+(-6+4) = -10x^{2}+7x-2$<br /><br />Therefore, the simplified expression is $-10x^{2}+7x-2$.
