To simplify the difference between the two expressions, we first need to write them down clearly:
Expression 1: 7x + 5x4 + 5
Expression 2: 7x4 + 5 + 9x
Now, we want to find the difference:
Difference: (7x + 5x4 + 5) – (7x4 + 5 + 9x)
Next, we can distribute the negative sign across the second expression:
= 7x + 5x4 + 5 – 7x4 – 5 – 9x
Now, we can combine like terms:
1. Combine the x terms: 7x – 9x = -2x
2. Combine the constant terms: 5 – 5 = 0
3. Combine the x4 terms: 5x4 – 7x4 = -2x4
Putting it all together, we have:
Simplified Difference: -2x4 – 2x
So, the simplified difference of the two expressions is: -2x4 – 2x.
