Given:

(x-y)²-4(x-y)

To Find:

The value of the given expression.

Solution:

Expanding the given expression,

x² - 2xy + y² - 4x + 4y.

x² - 4x - xy + y² + 4y - xy.

x(x - 4 - y) + y(y + 4 - x).

x(x - y - 4) - y(x - y - 4).

(x - y)(x - y - 4).

Hence, the factors of the given expression is (x - y)(x - y - 4).

x² - 2xy + y² - 4x + 4y. x² - 4x - xy + y² + 4y - xy. x(x - 4 - y) + y(y + 4 - x). x(x - y - 4) - y(x - y - 4). (x - y)(x - y - 4). Hence, the factors of the given expression is (x - y)(x - y - 4).

Histogram	Bar Graph
1. It consists of rectangles touching each other from each other with equal space	It consists of rectangles normally separated
2. The frequency is represented by the area of each rectangle	The frequency is represented by height. The width has no significance.
3. It is two dimensional where both the width (base) and the length (height of the rectangle) are important	It is one dimensional in which only length(height) matters while width is arbitrary.
