Simplify:
⟹ a ( a² + a + 1 ) + 5
⟹ a³ + a² + a + 5
( a³ + a² + a + 5 ) is the simplified form
If a = 0
⟹ a³ + a² + a + 5
⟹ (0)³ + (0)² + 0 + 5
⟹ 0 + 0 + 0 + 5
⟹ 5
If a = 0, the value of the polynomial will be 5
If a = 1
⟹ a³ + a² + a + 5
⟹ ( 1 )³ + ( 1 )² + 1 + 5
⟹ 1 + 1 + 1 + 5
⟹ 8
If a = 1, the value of the polynomial will be 8
If a = (-1)
⟹ a³ + a² + a + 5
⟹ (-1 )³ + (-1 )² + (-1 ) + 5
⟹ -1 + 1 - 1 + 5
⟹ - 1 + 5
⟹ 4
If a = 1, the value of the polynomial will be 8
