Soal Integral Kelas 11 Jika Pernyataan Benar Jawab B Jika Salah Jawab S

Answer 1

9. integral (12x²-4x)(2x+1) dx

= integral 4(3x²-x)(2x+1) dx

= integral 4(6x³+3x²-2x²-x) dx

= integral 4(6x³+x²-x) dx

= 4(6(1/4)x⁴+(1/3)x³-(1/2)x²)

= 6x⁴+(4/3)x³-2x²+C (B)

10. *)y =x²+4x+1

*)m = y' =2x+4 (salah)

*)subtitusikan titik ke kurva

3 =(1)²+4(1)+1 (salah)
