Can 8r squared- 3rs plus 10s squared be factored anymore?

The expression (8r^2 - 3rs + 10s^2) cannot be factored further using rational coefficients. It is a quadratic in terms of (r) and does not have rational roots, as the discriminant (b^2 - 4ac) (where (a = 8), (b = -3s), and (c = 10s^2)) is negative. Therefore, it remains in its current form as a sum of terms.
