Y = - 1.7043x^2 + 124.38x - 358.51

X - Y = 3.0062,

X - Y = 69.973

Step-by-step explanation:

Given equation is

-1.7043x² + 124.38x - 358.51 = y

This equation can be written as

x² - 72.98x + 210.35

Or, x² - 69.973x - 3.0062x + 210.35

Or, x (x - 69.973) - 3.0062 (x - 69.973)

So, (x - 69.973) (x - 3.0062)

Now this two factors are equal to y

∴ x - 69.973 = y and x - 3.0062 = y

Hence X - Y = 69.973 and X - Y = 3.0062 Answer
