Answer:
For n = 1, 150
for n = 2, 1164
Step-by-step explanation:
The answer for n = 1, is,
[tex]\int_{0}^{6}(2 \times x^{2} + 1)\times dx[/tex]
=[tex][2 \times \frac {x^{3}}{3} + x]_{0}^{6}[/tex]
=150
The answer for n = 2 is,
[tex]\int_{0}^{12}(2 \times x^{2} + 1)\times dx[/tex]
=[tex][2 \times \frac {x^{3}}{3} + x]_{0}^{12}[/tex]
= 1164
