Question

give possible expressions for the length and breadth of the rectangle in which it's area is 3y² + 25y - 18​

Answer 1

$\huge\mathbb\fcolorbox{blue}{lavender}{(y+9) or (3y-2)}$

3y² + 25y - 18

By factorisation

3y² + 27y - 2y - 1

Take Common

3y(y + 9) -2 (y + 9)

(y+9)(3y-2)

So the length and breadth of the rectangle can be both (y+9)(3y-2)
