Friday, we had a quiz covering square roots. There was no homework.
Today (Monday), we used colored tiles called Algebra Tiles to learn the processes of adding and subtracting polynomials.
For adding polynomials:
- Group/Collect like terms - the terms that have the same variable(s) to the same exponent
- Add the coefficients, keep the term like what they started as - same variable(s) to the same exponent
- Write the resulting polynomial
For subtracting polynomials (KFC or "add the opposite"):
- Keep the first polynomial the same
- Flip the signs of the second polynomial (positive to negative, and vice versa)
- Change the problem to addition
- Follow the steps for addition
Homework: finish today's packet. Students could checkout a packet of Algebra Tiles from me. They may use the tiles on next week's quiz (but they do not have to use them).
Quiz: Next Tuesday, October 13th covering adding, subtracting, and multiplying polynomials.
