Question

give possible expression for the length and breath of the rectangle whose area is 4a²+4a-3​

Answer 1

Step-by-step explanation:

Area of rect = lb ( lenght × breadth)

4a^2 + 4a -3

we can find tge lenght and breadth using splitting the middle term,

= 4a^2 + 4a -3

= 4a^2 + 6a -2a -3

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

= (2a +3)(2a - 3)

therefore, lenght :- 2a +3

breadth :- 2a -3
