Question

Simplify.
−1w + 4w4 + y4 – 3y4 – 2w – 3w4
A. −2w4 – 2y4
B. −w4y4 – 3w
C. w4 – 3w – 2y4
D. 12w4 + 2w – 3y4

Answer 1

lets put our like terms together..
-1w - 2w = -3w
4w^4 - 3w^4 = w^4
y^4 - 3y^4 = - 2y^4

now put it all together..
w^4 - 3w - 2y^4

any questions ?

Answer 2

like terms will have the same variable and the same exponent. If they are not like terms, you cannot add/subtract.
