Answer for screen readers

The simplified expression is $x^2 + 5y^3 - 1$.

Steps to Solve

  1. Identify like terms

First, identify the like terms in the expression:

  • The $x^2$ terms: $x^2$, $2x^2$, and $-2x^2$.
  • The constant terms: $4$, $-6$, and $1$.
  • The $y^3$ term: $5y^3$.
  1. Combine the $x^2$ terms

Now, combine the $x^2$ terms:

$$ x^2 + 2x^2 - 2x^2 = (1 + 2 - 2)x^2 = 1x^2 = x^2 $$

  1. Combine the constant terms

Next, combine the constant terms:

$$ 4 - 6 + 1 = (4 - 6 + 1) = -1 $$

  1. Write the simplified expression

Finally, combine the results:

$$ x^2 + 5y^3 - 1 $$

The simplified expression is $x^2 + 5y^3 - 1$.

More Information

Combining like terms allows for simplification of polynomial expressions, making them easier to work with in algebra. Recognizing and summing coefficients of like terms is a fundamental skill in algebra.

Tips

  • Forgetting to include all like terms when combining. Always double-check to ensure all similar terms are accounted for.
  • Incorrectly adding or subtracting coefficients. Pay close attention to signs.
