Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
we are given with
The polynomial x squared plus 2x minus 24

Hence the required combination is 6x and -4x
Rate tables are useful because it has something that stands for something else. For example,
I think this is how you do it...
