dibantu ya ka integral tak tentu kompleks

ini cara beserta jawaban, semoga membantu

misal:
u = 4x^2 + 6x - 9
du = (8x + 6) dx
du = 2(4x + 3) dx
1/2 du = (4x + 3) dx

= intg (4x + 3) * (4x^2 + 6x - 9)^9 dx
= intg (4x^2 + 6x - 9)^9 * (4x + 3) dx
= intg u^9 * 1/2 du
= 1/2 intg u^9 du
= 1/2 [ 1/10 u^10] + C
= 1/20 u^10 + C
= 1/20 (4x^2 + 6x - 9)^10 + C
