Answer:
x^2 + 2ax + a^2
Step-by-step explanation:
Well, not having enough information to solve the problem, what we can do is assign a name to what adds x and work from there, once we know the value we replace it with "a" what will be the letter used for that space blank and will serve us for any value
(x + a )^2 = __
being squared it repeats and multiplies
(x + a) * (x + a)
we multiply all terms with each other
x * x + x * a + x* a + a * a
solve
x^2 + 2ax + a^2
