Question

(4c^4+1)-(7c^3-3)+(2c^4+5c^3)

Answer 1

Answer: 6
`c^(4)` - 2
`c^(3)` + 4

Explanation:

`(4c^(4) +1)- (7c^(3) -3)+(2c^(4) + 5c^(3) )`

`= 4c^(4) +1-7c^(3) +3+2c^(4) +5c^(3)`

Combine like terms

`= 6c^(4) -2c^(3) + 4`

Answer 2

6c^4 - 2c^3 + 4

Explanation:

• (4c^4 + 1) - (7c^3 - 3) + (2c^4 + 5c^3) = ⇒ parenthesis
• 4c^4 + 1 - 7c^3 + 3 + 2c^4 + 5c^3 = ⇒ simplify, add up like terms
• 6c^4 - 2c^3 + 4 ⇒ answer
