Work out collect like terms instantly with clear inputs, formula shown and shareable results.
Like terms share exactly the same variable part, so their coefficients can be added. Grouping by power — x², x and constants — turns a long expression into standard quadratic form.
Standard form
ax² + bx + c with a, b, c each the sum of the matching coefficients
5x² + 5x − 5.
No for the value, but standard form lists descending powers, which makes comparison and factorising easier.
