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

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
