Question

Add.
(-5c4 + 2c2 - 6) and (6c4 - 2c2 + 5)

Answer 1

\[\Large -5c^4 + 6c^4 + 2c^2 - 2c^2 - 6 + 5\]

Answer 2

Since -5c^(4) and 6c^(4) are like terms,

subtract 6c^(4) from -5c^(4) to get c^(4).
c^(4)+2c^(2)-6-2c^(2)+5

2c^(2) and -2c^(2) are like terms,

add -2c^(2) to 2c^(2) to get 0
c^(4)-6+5

Add 5 to -6 to get -1.
c^(4)-1
