Question

By using paper cutting and pasting method, represent the factors of the quadratic expressions x2 – x − 6

Answer 1

Answer:

Every x2 represents the area of pink square of side x-units.

Therefore, to represent 2x2, use two pink squares of side x units each. Take x as 3 units.

Every x represents area of a green rectangular strip of dimensions (1 x x).

[For 5x, use 5 green strips each of dimensions (1 x x)]

Every (-x) is represented by a blue rectangular strip of dimensions (1 x x).

For (-5x), use 5 blue strips each of dimensions (1 x x).
