$intlimits^3_1 {(4x^3 + 3x^2)} , dx = x^4 + x^3 left | {3} atop {1} right.$

$= (3)^4 + (3)^3 - [(1)^4 + (1)^3]$

$= 81 + 27 - 2 = 106$

$intlimits^1_0 {(4x - 3)^2} , dx = intlimits^1_0 {(16x^2 - 24x + 9)} , dx$

$= frac{16}{3} x^3 - 12x^2 + 9x left | {1} atop {0} right.$

$= frac{16}{3} (1)^3 - 12(1)^2 + 9(1) - 0$

$= frac{16}{3} - 12 + 9$

$= frac{16}{3} - 3$

$= frac{16}{3} - frac{9}{3} = frac{7}{3}$
