Homework Statement
Evaluate the integral:
$$\int_{-\infty}^{\infty} dx *\dfrac {\delta (x^2-2ax)} {x+b}$$
Homework Equations
$$ x^2-2ax=0 $$
The Attempt at a Solution
I know that the delta function can only be none zero when $$ x=2a$$ so then I have the following integral:
$$\int_{-\infty}^{\infty} dx \dfrac {1} {2a+b} $$
But I'm not sure how to evaluate this integral, or even if this is the correct approach to the problem. Any guidance would be appreciated :)
