Analyze the following problems. A.
 * 1) If a square of side (3x-7y)m, what would be the effect on its enclosed area if (2y)m is added to one side and (12y)m to the other side?
 * 2) Is (2x-3)2 = (3-2x)2? Explain why or why not. If someone does not understand the rules on finding special products, what problem will he encounter? Why do you think so?
 * 3) Explain or illustrate how one can find square of 41 and 53 using the square of a sum of two terms?
 * 4) Explain or illustrate how one can find square of 39 and 58using the square of the difference of two terms?
 * 5) What problems will your encounter if you are not familiar with the types of special products?

B. 1. A square garden has a side of (x+7y)m. What would be the effect on its area if the length of each side is doubled? Halved? Explain. 2. A rectangular lot measures (5w+3z)cm by (5w-3z)cm. If (2w) cm is added to both dimensions, how is the area affected? Explain. 3. Using models, present a problem solving plan that will make use of the concept on special products. 4. Write a journal about the rules on finding special products. Send it to your classmate who was absent during our discussion of the topic through a letter, email, etc. Submit a copy of the journal. 5. Create a real life situation involving the concept on special products.
