Answer:

Mark me as the Brainliest!

Step-by-step explanation:

p(x) = 4x² + 4x -3

= 4x² -2x + 6x -3

= 2x(2x -1) +3(2x - 1)

= (2x - 1) (2x + 3)

So, The possible expressions are:

(2x-1) and (2x+3).

Step-by-step explanation:

p(x) = 4x² + 4x -3

= 4x² -2x + 6x -3

= 2x(2x -1) +3(2x - 1)

= (2x - 1) (2x + 3)

So, The possible expressions are:

(2x-1) and (2x+3).

length and breadth is (2x-1) and (2x+3).
