Simplify the following:
12 x^4+2 y^3-x^4-y^3
Group like terms in 12 x^4+2 y^3-x^4-y^3.
Grouping like terms, 12 x^4+2 y^3-x^4-y^3 = (2 y^3-y^3)+(12 x^4-x^4):
(2 y^3-y^3)+(12 x^4-x^4)
Combine like terms in 2 y^3-y^3.
2 y^3-y^3 = y^3:
y^3+(12 x^4-x^4)
Combine like terms in 12 x^4-x^4.
12 x^4-x^4 = 11 x^4:
Answer: |
| y^3+11 x^4
