Question

Simplify : a ( a square + a + 1 ) + 5 and find its value for a = 0 , a = 1​

Answer 1

Answer:

(i)value of a = 0

=a(a square + a + 1) + 5

=0(0 square + 0+1) + 5

= 0^3 + 0 + 1 +5

=0^3+1+5

=(0)(0)(0)+1+5

= 0+1+5

=1+5

=6(ans)

(ii)1(1^2+0+1)+5

=1^3+0+1+5

=(1)(1)(1)+0+1+5

=1+0+1+5

=2+5

=7(ans)
