Question
The Possible expressions for the length and breadth of the rectangle whose area is given by $4a^2 + 4a - 3$ is:
✓
Answer
$4a^2 + 4a - 3$
To find the length and breadth, we will factorize the given polynomial.
$= 4a^2 - 6a - 2a - 3$
$= 2a(a +3) - 1(2a + 3)$
$= (2a + 3) (2a - 1)$
Therefore, the Possible expressions for the length and breadth of the rectangle whose area is given by $4a^2 +4a - 3 $ is $(2a + 3)$ and $(2a - 1).$
