(8x + 3z - 8z^2) + (4y - 5z)
You need to add two polynomials.
1. Drop the parentheses since they are not needed.
2. Combine like terms. Like terms are terms that have the same variable part. To have the same variable part, the terms must have the same variables and the same exponents.
(8x + 3z - 8z^2) + (4y - 5z) =
Drop the unnecessary parentheses.
= 8x + 3z - 8z^2 + 4y - 5z
Combine like terms.
= 8x + 4y + 3z - 5z - 8z^2
= 8x + 4y - 2z - 8z^2
Answer: 8x + 4y - 2z - 8z^2
