Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)
