-18x-12=4
Iam not sure if that’s what you want but basically I multiplied the numbers inside the bracket by -6
Given:


To find:
The sum of m and n.
Solution:
We have,


The sum of m and n is:

Combining the like terms, we get



Therefore, the sum of m and n is
.
Distribute the x3 to each number. The coefficient stays the same but add exponent (3) onto each x. Final answer is: x to the seventh power plus 8X to the sixth power plus 2X to the fifth power +18 X to the fourth power +9x the third power
You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
