The answer
<span>1/(a+2) = 1/a + 1/2 this equation is equivalent to </span><span>1/(a+2) = 2+a / 2a, it means
</span>1x( <span>2a) = </span>(a+2) x(2+a) , 2a= (a+2)² =a²+4+4a, so we have a²+2a+4=0, and this last doesnt have any solution (there is no value of a verifying a²+2a+4=0)
so the answer is <span>A. no real values a.</span>
