Detail solution

    ErfRule(a=-2, b=0, c=0, context=E**(-2*x**2), symbol=x)

  1. Add the constant of integration:

    2πerf(2x)4+constant\frac{\sqrt{2} \sqrt{\pi} \operatorname{erf}{\left(\sqrt{2} x \right)}}{4}+ \mathrm{constant}


The answer is:

2πerf(2x)4+constant\frac{\sqrt{2} \sqrt{\pi} \operatorname{erf}{\left(\sqrt{2} x \right)}}{4}+ \mathrm{constant}
