When I put ^2 that means it is squared.

I'd use the quadratic formula:
x = (a +/- sqrt(a^2 + 24a^2))/2
x = (a +/- sqrt(25a^2)) / 2
x = (a +/- 5a) / 2
x = 3a, -2a
Which means the equation factors as:
(x - 3a)(x + 2a)

I'm assuming that you want this factored.
Since the x^2 term has a coefficient of 1, this problem is not too difficult. The second term has a coefficient of -1 and the last term has a coefficient of -6, so we are looking for two numbers that multiply to get -6 and add up to -1.
(-3)*2 = -6 and
(-3) + 2 = -1 so
x^2 -ax -6a^2
=(x - 3a)(x + 2a)
You can check using FOIL, if you would like.

What is the question? Are you trying to factor it? If so:
(x-3a)(x+2a)

(x-3a)(x+2a) are the factors.

x^2-ax-6a^
=x^2-3ax+2ax-6a^2
=x(x-3a)+2a(x-3a)
=(x-3a)(x+2a)
