so what i did was......

the limits of integration are from -2 to 2

what i did was: \[\int\limits_{-2}^{0} (2x+x)\] and \[\int\limits_{0}^{2} (2x-x)\]

so the inside of both, repectively, would be 3x and x, thats all i woould hav eto integrat

Using symmetries ... \[\int\limits_{-2}^{2}(2x-|x|)dx=-2\int\limits_{0}^{2}xdx\]
