Write a function that describes a relationship between two quantities. Two polynomial functions are given.
d(x) = 2x^3 - x + 12
c(y) = 5y^2 - 9
Find 3d(x) * c(y) and write an equivalent expression.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
