otherwise. 5. Number the answers EXACTLY according to the numbering system used in this investigation. 6. Write neatly and legibly. Factorisation is a method of factoring a number or a polynomial. The polynomials are decomposed into products of their factors. A trinomial is an expression that contains three terms. When you expand binomials such as (x+2)(x 5), you get an answer in the form of a trinomial: x2-3x-10 The inverse process of writing trinomials into the product of two binomials is called factorisation. Algebra tiles are mathematical manipulatives that allow learners to better understand ways of algebra thinking and the concepts of algebra. Each tile is based on area as outlined below: NAME MODEL ACTIVITY 1 1.1 Carry out the following steps: Step 1: Write down the algebraic expression modelled by the algebra tiles in (a) - (d). Step 2: Look at the tiles and find the factors by writing down the factors of x² and the number of x tiles in each row in the spaces marked a and b in the figures (do not forget to include the sign). Step3:write down the factors (using brackets to separate them) in step 2 and calculate the product in each case. Use the table below to reord the answers​
