Answer:
Step-by-step explanation:
a. a^4 - 2ab^2 - 2ab^2 + 4b^4 = a^4 - 4ab^2 + 4b^2
b. 49x^2 - 14x + 1
c. 25a^2 - 20ab^4 + 4b^8
d. x^2 - 144
e. -16n^6 - 28n^3 + 28n^3 + 49 = -16n^6 + 49
Just subtract each term from the next term.
So:
2nd term minus 1st term = 0.26 - 0.36 = -0.1
3rd term minus 2nd term = 0.16 - 0.26 = -0.1
etc
So common difference is -0.1
