Question

Give possible expression for the length and breadth of the rectangle,which has area =a square - 6a+8

Answer 1

Step-by-step explanation:

area of rectangle= length x breadth

length x breadth= a²-6a+8

on solving this quadratic equation

length x breadth= a²-4a-2a+8

length x breadth= a(a-4)-2(a-4)

length x breadth= (a-2)(a-4)

so.......

length=(a-2)

breadth=(a-4)
