Answer:
[tex]\frac{5}{2} x^2[/tex]
Step-by-step explanation:
For simple antiderivatives like this, I usually add a degree to the x. ([tex]x^{n+1}[/tex])
In this case it is [tex]x^{1+1}[/tex] or [tex]x^{2}[/tex].
Then, I take the coefficient and divide it by the new power degree. ([tex]\frac{a}{n} x^{n}[/tex])
In this case it is [tex]\frac{5}{2} x^{2}[/tex].
