Evaluate the integral. (Give your answer as an improper fraction.)

Ok my work:

b/c of abs value law x { x when x>/= to 0

{ -x when x<0

Intergral from -2 to 0 (x-2(-x))dx + Integral from 0 to 3 (x-2(x)) dx

= integral from -2 to 0 (3x) dx + integral from 0 to 3 -x dx

Antiderivative= (3x^2)/2 | -2 to 0 intervals

Antiderivative= -x^2/2 | 0 to 3 intervals

you plug in each and i got

= (0 - (3(4))/2) + ( 9/2 - 0) = -1.5 which they said was wrong?! and they wanted as an improper fraction so that is -3/2 but I only have one more try to enter in an answer and I want to be 100% sure I am correct.

Any help greatly appreciated!!
