Answer:
2x³ + 2x
Step-by-step explanation:
(x² + x³ + x² + x) - (x² - x³ + x² - x)
= x² + x³ + x² + x - x² + x³ - x² + x
Gathering like terms...
x³ + x³ +x² + x² -x² - x² + x + x
= 2x³ + 2x
Answer:
the difference between the polynomial is=(b)2x³+ 2x
Step-by-step explanation:
There are given two polynomials.
We can calculate the answer by subtracting those polynomials.
by substracting, we will get the answer
= x² + x³ +x² +x - x² + x³ + x² - x
=2x³ + 2x
