Poin gede nih. Tolong jawab sama caranya dong. Mau pake belajar. Mohon bantuannya ya.

ₐ³∫ 3x² + 2x+1 = 25
[x³ + x² +1]³ₐ  =25
(27 + 9 +3) - (a³ + a² +1)= 25
a³ + a² +1 = 39-25 = 14
a = 2
1/2 a = 1


₀⁴ ∫ f(x) dx = 2
₂⁴∫ 2. f(x) dx = 2 → 2 ₂⁴∫ f(x) dx = 2→ ₂⁴ ∫f(x) dx = 1

₀²∫ f(x) dx + ₂⁴∫ f(x) dx = ₀⁴∫ f(x) dx
₀²∫ f(x) dx = ₀⁴∫ f(x) dx -  ₂⁴∫f(x) dx = 2 -1 = 1
