Question

ques4 b part solve it fast

Answer 1

for a=0...
$0( {0}^{2} + 0 + 1) + 5 \\ = 5$
for a=1...
$1( {1 }^{2} + 1 + 1) + 5 \\ = 1(1 + 1 + 1) + 5 \\ = 3 + 5 \\ = 8$
for a=-1...
$- 1( { - 1}^{2} + ( - 1) + 1) + 5 \\ = - 1(1) + 5 \\ = - 1 + 5 \\ = 4$

Answer 2

(i) Putting a=0
0(0^2+0+1)+5
=0+5=5
(ii) putting a=1
1(1^2+1+1)+5
=1(3)+5
=3+5
=8
(iii) Putting a=-1
-1{(-1^2)+(-1)+1}+5
-1(1)+5
=5-1
=4
