Question

Area of a rectangle is given as (x

2 + x − 12) square units, then the expressions of length and

breadth of it are

Answer 1

(x-3) (x-4)

Step-by-step explanation:

Splitting the middle term

x²+4x-3x-12

taking x common

x(x+4) -3(x+4)

taking (x-4) common

(x-3) (x-4)

so lenght = (x-3)

breadth = (x-4)

or

vice-versa
