Response:

$3X^{2} - 12X - 36 = 0$

A quadratic equation has solutions of 6 and -2.

Thus, if the variable is denoted by X, the factors of the polynomial function will be (X - 6) and (X + 2).

Thus, the equation can be represented as

(X - 6)(X + 2) = 0

⇒

$X^{2} - 4X - 12 = 0$

If the leading coefficient is 3, we can express the equation as

(Response) $3X^{2} - 12X - 36 = 0$

(2 6/7) divided by (1 2/3) equals x over 1.
Cross-multiply and convert mixed numbers to improper fractions:
(5/3)x = 20/7
Solving for x:
x = (20/7) × (3/5)
x = 60/35, which simplifies to 1 5/7 songs per minute.
