Question

simplify the algebraic expression by combining like (or similar) terms.
$2x - y^2 + 4 - 2y^2 - x + 4$

Explanation:

Step1: Group like terms

Group the \(x\)-terms, \(y^2\)-terms, and constant terms together: \((2x - x)+(-y^2 - 2y^2)+(4 + 4)\)

Step2: Combine like terms

For the \(x\)-terms: \(2x - x=x\)
For the \(y^2\)-terms: \(-y^2 - 2y^2=-3y^2\)
For the constant terms: \(4 + 4 = 8\)

Answer:

\(x - 3y^2 + 8\)
