y = 18x^2 - 36x + 10

Explanation:

The standard form of an equation is:
y = ax^2 - bx + c

So, you have to develop the right member which is the form :
(a + b) (c + d)
We develop as :
(a*c) + (a*d) + (b*c) + (b*d)

So :
y = (3x - 5)(6x-2)
y = (3x * 6x) + (3x * -2) + (- 5 * 6x) + (-5 * -2)
y = 18x^2 - 6x -30x + 10
y = 18x^2 - 36x + 10
