We see that each green rectangle tile is equal to seven blue square tiles. To move them, we need to pair them up with a different colored square. An error occurred trying to load this video. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons The teacher will work out a few examples on the overhead so the students can see how to solve the problems. We find 3n + 2 on the left side of the equation. Given a quadratic equation, the student will use tiles to factor and solve the equation. So that means our x is equal to 7. On the right side, we have ten blue square tiles to represent our 10. It helps us to see just what quantities we're working with. If a = 0, then the equation is linear, not quadratic, as there is no ax² term. This tells us that each rectangle tile equals 4 square tiles. 1. This gives us. You would select three tiles … For example, if the expression is 3x– 2, place 3 green x tiles and 2 red 1 tiles in one half of the workspace. Expressions are built up from tiles corresponding to each of x 2, −x 2, x, −x, 1, and −1, where the shape and colour indicates the class of tile. We do this by moving the square tiles.
