Question

Give possible expressions for the length and the breadth of the rectangle whose area is 12x² - 35x + 25

Answer 1

12x² - 35x + 25
= 12x² - 20x - 15x + 25
= 4x(3x - 5) - 5(3x - 5)
= (3x - 5)(4x - 5)
Thus,
Length = (3x - 5) and breadth = (4x - 5)
OR
Length = (4x - 5) and breadth = (3x - 5)
