∫01(x2−5x+4) dx\int\limits_{0}^{1} \left(x^{2} - 5 x + 4\right)\, dx 
Integral(x^2 - 5*x + 4, (x, 0, 1))
Detail solution

  1. Integrate term-by-term:

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

      ∫x2 dx=x33\int x^{2}\, dx = \frac{x^{3}}{3}

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

      ∫(−5x) dx=−∫5x dx\int \left(- 5 x\right)\, dx = - \int 5 x\, dx

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

        ∫5x dx=5∫x dx\int 5 x\, dx = 5 \int x\, dx

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

          ∫x dx=x22\int x\, dx = \frac{x^{2}}{2}

        So, the result is: 5x22\frac{5 x^{2}}{2}

      So, the result is: −5x22- \frac{5 x^{2}}{2}

    1. The integral of a constant is the constant times the variable of integration:

      ∫4 dx=4x\int 4\, dx = 4 x

    The result is: x33−5x22+4x\frac{x^{3}}{3} - \frac{5 x^{2}}{2} + 4 x

  2. Now simplify:

    x(2x2−15x+24)6\frac{x \left(2 x^{2} - 15 x + 24\right)}{6}

  3. Add the constant of integration:

    x(2x2−15x+24)6+constant\frac{x \left(2 x^{2} - 15 x + 24\right)}{6}+ \mathrm{constant}

The answer is:

x(2x2−15x+24)6+constant\frac{x \left(2 x^{2} - 15 x + 24\right)}{6}+ \mathrm{constant}
