How do you simplyfy -x squared + 4/2x

The solution for the given expression is 0 ,  2

Step-by-step explanation:

Given expression as :

- x² + x = 0

or, - 2 x² + 4 x = 0

or, 2 x ( -x + 2 ) = 0

or, ( - x + 2 ) ( 2 x ) = 0

or, 2 x = 0

∴  x = 0

and ( - x + 2 ) = 0

Or, - x = - 2

∴   x = 2

Hence The solution for the given expression is 0 ,  2  Answer
