1 answer

The expression given is \(-6(4x - 213)\). To correctly expand this expression, we need to distribute \(-6\) to both terms inside the parentheses.

The correct steps are:

  1. Multiply \(-6\) by \(4x\): \[ -6 \cdot 4x = -24x \]

  2. Multiply \(-6\) by \(-213\): \[ -6 \cdot -213 = 1278 \]

So, the expanded expression is: \[ -24x + 1278 \]

Now, looking at the options provided:

The correct response is: No, the student should have multiplied 4x and −213 by −6.
