integral of 1/2 x-1

Solution

\int \frac{1}{2} x - 1 d x

Solution

\frac{x ^{2}}{4} - x + C

Solution steps

\int \frac{1}{2} x - 1 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{2} x d x - \int 1 d x

\int \frac{1}{2} x d x = \frac{x ^{2}}{4}

\int 1 d x = x

= \frac{x ^{2}}{4} - x

Add a constant to the solution

= \frac{x ^{2}}{4} - x + C
