Flashcard 8 - Math Reasoning Flashcard Set for the GED Test

To multiply two polynomials, multiply each term of the first polynomial by each term of the second polynomial. Combine like terms. Simplify.

Example:

Multiply \((x^2+3xy+5)\) by \((2x-y)\).

\[2x(x^2+3xy+5) - y(x^2+3xy+5)\] \[2x^3+6x^2y+10x - (x^2y+3xy^2+5y)\] \[2x^3 + 5x^2y - 3xy^2 + 10x - 5y\]
