प्रश्न

The following expression is the area of a rectangle. Find the possible length and breadth of the rectangle.

x2 – 7x + 10

योग

उत्तर

We have,

Area of rectangle = x2 – 7x + 10

= x2 – (5 + 2)x + 10

= x2 – 5x – 2x + 10

= x(x – 5) – 2(x – 5)

= (x – 5)(x – 2)

 ∴ The possible length and breadth are (x – 5) and (x – 2).
