Question

Give possible expressions for the length and breadth of the rectangle whose area is given by 4a^2+4a-3.

Answer 1

area of rectangle is= length X breadth

so it length and breadth can be factor of this expression.

4 {a}^{2}  + 4a - 3 \\ 4 {a}^{2}  + 6a  - 2a - 3

2a(2a + 3) - 1(2a + 3) \\ (2a + 3)(2a - 1)

so length can be :(2a+3)

breadth can be :(2a-1)
