nilai s diatasnya 1 dibawahnya -2 lalu x pangkat 2 (x+2)pangkat 2 dx adalah

x²(x+2)² dx
= x²(x²+4x+4) dx
= (x⁴+4x³+4x²) dx
= (1/5)x^5 + x⁴ + (4/3)x³
= {(1/5)(1)^5 + (1)⁴ + (4/3)(1)³} - {(1/5)(-2)^5 + (-2)⁴ + (4/3)(-2)³}
= {1/5 + 1 + 4/3} - {-32/5 + 16 - 32/3}
= {38/15} - {-16/15}
= 38/15 + 16/15
= 54/15
= 18/5
