Hi mate !!
Here's the answer !!
Let the consecutive numbers be x and x + 2
So it is given that,
= ( x ) ( x + 2 ) = 728
= x² + 2x = 728 = 0
=> x² + 2x - 728 = 0
=> x² + 28x - 26x - 728 = 0
=> x ( x + 28 ) -26 ( x + 28 ) = 0
=> ( x - 26 ) ( x + 28 ) = 0
=> x = 26 , - 28
So the two numbers are 26 and 28 or - 28 or - 26.
Hope my answer helps !!
Cheers !!
