Nothing

The numbers don't have to be whole numbers, and I'm pretty sure they can be negative as well

x2 +11x +30

16x2 - 16x-12

2x2y +4xy+6xy2

10a2-5a-15

20N2 + 47N +24

8xy3z2 - 12x3y2z2+20x2y3z3

a^3–a a3–a

The product of two consecutive odd integers is 1 less than 4 times their sum. Find the two integers. Answer in the form of paired points with the lowest of the two integers first.

Write as a product x^2–x^4 x2–x4
