To expand the expression \(-4(6a - 5)\), you will distribute \(-4\) to each term inside the parentheses:
\[ -4(6a) + (-4)(-5) \]
Calculating each term:
- \(-4 \times 6a = -24a\)
- \(-4 \times -5 = 20\)
Putting it all together, the expanded expression is:
\[ -24a + 20 \]
So, \(-4(6a - 5) = -24a + 20\).
