Which statement is true about the factorization of 30x2 + 40xy+51y2

prime

not factorable over the reals

Step-by-step explanation:

30x^2+40xy+51y^2 is not factorable (also know as prime)

because the discriminant is negative.

That is when I computed b^2-4ac, in this case 40^2-4 (30) (51) = -4520.

If the discriminant is negative, then it isn't factorable over the reals.
