Follow the structure before calculating

A term is a product of a coefficient and variable powers. Addition and subtraction separate terms; parentheses organize whole polynomials. Keep those boundaries clear before counting terms, finding degrees or applying an operation.

Each customized student worksheet and its answer key use the same generated questions. Start with a focused set of structures, check the worked reasoning, then generate a fresh set when the learner is ready.

Learning objective

What this activity builds

Multiply every polynomial term by the outside monomial and simplify.

Worked example

Expand −2x(3x² − 4x + 5).

−6x³ + 8x² − 10x.

The three products are (−2x)(3x²), (−2x)(−4x) and (−2x)(5). The two negative factors in the middle product give a positive term.

Teaching notes

Make the practice count

  • Draw one connection from the outside factor to every term.
  • Multiply coefficients before combining variable powers.
  • Keep each term’s sign visible.
  • Check that no term was skipped.
