Use the quadratic formula

x = (-b +/- sqrt(b^2 - 4ac))/(2a), where the quadratic equation is in the form y = ax^2 + bx + c.

So if you have 5x^2 + 13x + 6, you solutions will be
(-13 +/- sqrt(13^2 - 4(5)(6)))/(2(5))
= (-13 +/- 7)/(10)
= -2 or -0.6

You then subtract you solutions from x.
So you have (x- (-2))(x - (-0.6)) = (x+2)(x+0.6). Now it's factored.

Your post was right, the only thing you forgot was you always have to put your highest coëfficient up front. So 5*(x- (-2))*(x - (-0.6)) = 5*(x+2)*(x+0.6)

You got:
ax^2+bx+c
Search ∆=b^2−4ac
If ∆>0 there are 2 solutions
If∆=0 there is 1 solution
If ∆<0 there is no solution
Search for x1 and x2
x1=(−b + √∆)/2a
x2=(−b - √∆)/2a
Factoring:
ax^2+bx+c
=(x-x1)(x+x2)

So yeah, you have to subtract the solutions you got from the quadratic formula from x, multiply them all together, and multiply by a.
5(x-(-2))(x-(-0.6)) = 5(x+2)(x+0.6)

No wait, it's right, because if it were say (2x+3)(3x+2), you'd just have 6(x+3/2)(x+2/3)

Well yeah technically speaking this only works if the polynomial has zeroes over the real numbers. But then at the same time you can argue it always works as long as you work in the complex numbers. Or you can argue it hardly ever works if you only work in the integer numbers. When it comes to math you can always dig deeper into the specifics to be exacter in what you're saying. Pretty sure as far as OP goes what you said is enough to go with

Mistake in factoring it's supposed to be
a(x-x1)(x-x2)

The quadratic formula is two separate equations.
"+/-" just means one equation is a plus sign and the other equation is a negative sign. You don't literally divide by a minus sign, if that's your issue.
