To factor the given function, find a term that is divisible by both terms. For this problem, the factor would be 2, since 2x^2 and -18 are both divisible by 2.
2(x^2 - 9)
You could further factor out x^2 - 9 because it is factorable by (x - 3) and (x + 3). Thus, it would be
2(x -3)(x+3)
The steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.
<h3>How to determine the steps you need to do to evaluate the expression</h3>
The expression is given as:
-5(-2)
The above expression represents the product of -5 and -2
This can be interpreted as:
- Removal of 5 groups of -2; to remove means negative
- Dragging zero pairs of 5 and 2 to the interactive window
Hence, the steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.
