Question 2 - Think & Reflect Box 2 (Page 79) Lay out algebra tiles for 𝑥^2+11𝑥+30 in such a way that you will see its factors. We need a grid of 30 unit tiles in the corner that perfectly lines up with the 11𝑥 tiles. What two numbers multiply to 30 and add up to 11 ? It's 5 and 6 So, we build a rectangle with sides (𝒙+𝟓) and (𝒙+𝟔)
