Question

Find length and breath of 4x^2+4x-3

Answer 1

Step-by-step explanation:

4x² + 4x -3

4x² + 6x - 2x -3

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

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

x= 1/2

and

x= -3/2

So lenght and breadth will be 1/2 and -3/2

Answer 2

4x^2 + 4x - 3=0

By Middle Term Splitting

=>4x^2+6x-2x-3=0

=>2x(2x+3)-1(2x+3)=0

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

So, 2x - 1 =0 2x + 3=0

2x= 1. 2x= -3

x= 1/2. x= -3/2

So length and breadth are -3/2 and 1/2. (According to this much question only)
