<u>Answer:</u>
- 28 is the answer to the multiplication problem.
<u>Step-by-step explanation:</u>
<u>We can cancel out the 6 with the 24 because it is a multiple of 6.</u>
- -24 x -7/6
- => -(4 x 6) x -7/6
- => -4 x -7
<u>Now, let's multiply. Remember, minus multiplied with another minus results positive.</u>
- => 28
Hence, <u>28 is the answer to the multiplication problem.</u>

Answer:
Step-by-step explanation:
We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.
Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)
Denominator (factoring by grouping):
x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)
Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:
x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)
