integral from 2 to 4 of |x^2-4x+3|

\int_{2}^{4} x^{2} - 4 x + 3 d x

2

Solution steps

\int_{2}^{4} x^{2} - 4 x + 3 d x

Eliminate Absolutes

= \int_{2}^{3} - x^{2} + 4 x - 3 d x + \int_{3}^{4} x^{2} - 4 x + 3 d x

\int_{2}^{3} - x^{2} + 4 x - 3 d x = \frac{2}{3}

\int_{3}^{4} x^{2} - 4 x + 3 d x = \frac{4}{3}

= \frac{2}{3} + \frac{4}{3}

Simplify

\frac{2}{3} + \frac{4}{3} : 2

= 2
