to interpret geometrically the factors of a quadratic expression of type x2+bx+c using square grids, strips and paper slips
Dear student
Aim To represent
Material Required Paper grid, rectangular strips and slips.We call them algebra tiles.
Procedure
To represent this we need 1 square tile representing , 5 algebra tiles representing x and 6 algebra tiles representing 1.
· By splitting the middle term of the given polynomial we get the expression
· Place a square tile of dimension 10X10 representing .
· Add 3 tiles of dimension 10 X 1 each to any side of the tile .The area of new shape formed represents .
· Add 2 tiles of dimension 10 X 1 each to the side adjacent to the previous side. The area of new shape formed represents .
· Add 6 tiles of dimension 1 X 1 each to complete the rectangle. The area of new shape formed represents .
