What is (7/5, 6/5)?
This is the name of the tune more commonly known as the Quadratic Formula Song.
What is "Pop Goes the Weasel"?
This person (featured in the movie Hidden Figures) said:
"The early trajectory was a parabola, and it was easy to predict where it would be at any point. Early on, when they said they wanted the capsule to come down at a certain place, they were trying to compute when it should start. I said, ‘Let me do it. You tell me when you want it and where you want it to land, and I’ll do it backwards and tell you when to take off."
This is the positive root of 2x2+12x-80=0.

What is 6?
Out of the three lines
x+2y=1 and 3x-2y=4 and 4x+2y=-6

What is 3x-2y=4?
This is Dr.V's middle name.
What is Kendrick?
This 16th century French mathematician was known for developing the "new algebra" and using different letters to represent numbers: vowels (such as a, e, i,...) for unknowns and consonants (such as r, s, t,...) for known parameters.

A quadratic x2+bx+c has integer coefficients and roots r and s. This is the number of possible pairs (b,c) given that r2s+s2r=10.
What is 8?
This is the number of integers k such that the parabolas
