integral

gunakan  ∫ a x ⁿ  d x=  a/(n+1)  xⁿ⁺¹  + c

a. ∫(3x³ + 4x²)/ x  dx
= ∫ 3x² + 4x  dx
= 3/(2+1) x²⁺¹ + 4/(1+1) x¹⁺¹ +c
= 3/3 x³ + 4/2 x² + c
= x³ + 2x² + c

b. ∫ 3x(x - 2) dx = ∫3x² - 6x dx = x³ - 3x² + c

c. ∫ 4x² + 5x - 10 dx = 4/3 x³ + 5/2 x² - 10x + c

d. ∫(x+5)(2x-1) dx = ∫ (x² + 9x - 5 dx
= 1/3 x³ + 9/2  x²  - 5x + c
