Solve ∫ 2x dx = x^2 + C

Method: quy tắc lũy thừa + hằng số nhân. Verified step-by-step solution with our free AI math solver.
Problem

2xdx\int 2x \, dx

Step-by-step solution

  1. Đưa hằng số ra ngoài: 2xdx=2xdx\int 2x \, dx = 2 \int x \, dx.

  2. Áp dụng quy tắc lũy thừa: xdx=x22+C\int x \, dx = \frac{x^2}{2} + C.

  3. Nhân: 2x22=x22 \cdot \frac{x^2}{2} = x^2.

  4. Thêm hằng số: x2+Cx^2 + C.

Answer

x2+Cx^2 + C
