Integral(7*x^3 + 4*x^2, (x, 0, 1))
Detail solution
  1. Integrate term-by-term:

    1. The integral of a constant times a function is the constant times the integral of the function:

      7x3dx=7x3dx\int 7 x^{3}\, dx = 7 \int x^{3}\, dx

      1. The integral of xnx^{n} is xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

        x3dx=x44\int x^{3}\, dx = \frac{x^{4}}{4}

      So, the result is: 7x44\frac{7 x^{4}}{4}

    1. The integral of a constant times a function is the constant times the integral of the function:

      4x2dx=4x2dx\int 4 x^{2}\, dx = 4 \int x^{2}\, dx

      1. The integral of xnx^{n} is xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

        x2dx=x33\int x^{2}\, dx = \frac{x^{3}}{3}

      So, the result is: 4x33\frac{4 x^{3}}{3}

    The result is: 7x44+4x33\frac{7 x^{4}}{4} + \frac{4 x^{3}}{3}

  2. Now simplify:

    x3(21x+16)12\frac{x^{3} \cdot \left(21 x + 16\right)}{12}

  3. Add the constant of integration:

    x3(21x+16)12+constant\frac{x^{3} \cdot \left(21 x + 16\right)}{12}+ \mathrm{constant}


The answer is:

x3(21x+16)12+constant\frac{x^{3} \cdot \left(21 x + 16\right)}{12}+ \mathrm{constant}
