integralkan... beserta jalanya ya kak... yg nolongin kudoain dpet pahala yg besar.aminnn

Penyelesaian:

1. ∫ (6 - 3x) dx
= 6x - 3/2 x^2 + c

2. ∫ (x - 5)(x + 1) dx
= ∫ x^2 - 4x - 5 dx
= 1/3 x^3 - 2x^2 - 5x + c

3. ∫ (3x^2 + 6x - 5) dx
= x^3 + 3x^2 - 5x + c

4. ∫ 4x^2√x dx
= ∫ 4x^2.x^1/2 dx
= ∫ 4x^5/2 dx
= 8/7 x^7/2 + c

5. ∫ x√x / 9√x dx
= ∫ x/9 dx = ∫ 1/9 x dx
= 1/18 x^2 + c
