Is the product of -5+ XNX +4 equal to the product of 5+ X and X -4

No

Step-by-step explanation:

(-5 + x)( x + 4)= -5*(x+4) +x*(x +4 )

                = -5x -20 +x² + 4x

                 = -5x + 4x + x² -20   =   -x + x² -20

                =  x² - x - 20

(5 + x) (x -4) = 5*(x-4) + x (x-4)

                  = 5x - 20 + x² - 4x

                  = 5x - 4x  +x²  -20 = x + x² - 20

                 = x² + x - 20
