(10-6i)-(2+3i) 8-3i -9i+8 12+3i 8-9i

To solve the expression \((10-6i)-(2+3i)\), we need to subtract the real parts and the imaginary parts separately.<br /><br />First, let's subtract the real parts:<br />\[ 10 - 2 = 8 \]<br /><br />Next, let's subtract the imaginary parts:<br />\[ -6i - 3i = -9i \]<br /><br />Combining these results, we get:<br />\[ 8 - 9i \]<br /><br />So, the correct answer is:<br />\[ 8 - 9i \]<br /><br />Therefore, the correct choice is:<br />\[ \boxed{8-9i} \]
