please kk tolong bantu dijawab

1)
integral (1/2 x - 1/3)^5 dx
= integral (1/32 x^5 - 5/48 x^4 + 5/36 x^3 - 5/54 x^2 + 5/162 x - 1/243) dx
= 1/192 x^6 - 1/48 x^5 + 5/144 x^4 - 5/162 x^3 + 5/324 x^2 - 1/243 x + C


2)
integral (4x^3 + 12x + 5)(x^2 + 1) dx
= integral (4x^5 + 16x^3 + 5x^2 + 12x + 5) dx
= 2/3 x^6 + 4x^4 + 5/3 x^3 + 6x^2 + 5x + C
