1. Choose ONE question from EACH group

2. Use the "rectangle method" to explain how to simplify each expression.

3. Also show how you would use distributive law to simplify each expression.

- Complete both questions in the same sheet of paper.
- Write down the question number clearly.
- Label the diagrams neatly. It should have its 'dimensions/values' clearly indicated at each 'part' of the rectangles.

Q1a. (a + 3)(a + 5)

Q1b. (3m + n)(2m + 5n)

Q1c. (5x + 3)^2

Q1d. (a^2 + a + 2)(a + 3)

Group 2 Questions

Q2b. (c + 4d)(c - 2)

Q2c. (b + 4)(h - k)

Q2d. (2a + 3b) (a - 4c)

why only group 1 and 2?

ReplyDeleteMiss Loh wrote choose 1 question from each grp. But we are not going according to any grp so we can choose which questions we want to do.
