Step-by-step explanation:
Here,
[tex]1. \: (2x + 2) + (3 - 5x)[/tex]
open brackets,
[tex]2x + 2 + 3 - 5x[/tex]
[tex] = - 3x + 5[/tex]
now,
[tex]2. \: (3x - {4x}^{4} ) + (2x + {5x}^{4} [/tex]
open brackets,
[tex] = 3x - {4x}^{4} + 2x + {5x}^{4} [/tex]
simplifying like terms,
[tex] = {x}^{4} + x[/tex]
Hope it helps...
