The expression be (5x³ - 5x - 8) + (2x³ + 4x + 2) then we get 7x³ - x - 6.
<h3>What is an expression?</h3>
An expression exists as a set of terms connected utilizing the operations +, -, x or ÷, for example, 4x − 3 or 5 x 2 − 3xy + 17.
An equation exists as a statement with an equals sign, which states that two expressions exist equal in value, for example, 4b − 2 = 6.
The given expression is
(5x³ - 5x - 8) + (2x³ + 4x + 2)
simplifying the above equation, we get
5x³ - 5x - 8 + 2x³ + 4x + 2
Combine like terms,
(5x³ + 2x³) + (-5x + 4x) + (-8 + 2)
adding similar elements, we get
7x³ + (-x) + (-6)
7x³ - x - 6
Therefore, the simplified form of the given expression is 7x³ - x - 6.
