6 - (-6)
This is because two negatives make a positive, so you’ll be adding 6+6 which equals to 12 not 0
(x^2)+4x-12=48
I Hope this is what you were looking for. If it isn't this just plug it in
x=6
4m + 5
Remove the parenthesis and collect like terms
3m + m + 5 = (3m + m) + 5 = 4m + 5
Are you add or subtracting
SUBTRACTION
3 1/4- 1 1/4 = 1 3/4
Addition
