Answer 1

Answer....

$\sf \:i) \: a \: = 0 \\ \sf \: a(a + a + 1) + 5 \\ \sf = 0(0 + 0 + 1) + 5 \\ \sf = 0 + 0 + 0 + 5 \\ \sf = 5 \\ \\ \sf \: ii) \: a = 1 \\ \sf a(a + a + 1 + 5 \\ \ = 1(1 + 1 + 1) + 5 \\ \sf = 1 + 1 + 1 + 5 \\ \sf = 8 \\ \\ \sf \: iii) \: a = - 1 \\ \sf \: a(a + a + 1) + 5 \\ \sf = - 1( - 1 + ( - 1) + 1) + 5 \\ \sf = - 1( - 1 - 1 + 1) + 5 \\ \sf = 1 - 2 + 5 \\ \sf = 4$
