Expanding the left side of the equation, we get:
6x(7) - 6x(3) - 2x(21x) + 2x(6) = 3 - 30x
42x - 18x - 42x^2 + 12x = 3 - 30x
Subtracting 3 from both sides:
42x - 18x - 42x^2 + 12x - 3 = -30x
Rearranging and simplifying:
-42x^2 + 36x - 3 = -30x
Adding 30x to both sides:
-42x^2 + 66x - 3 = 0
This quadratic equation is now in the form of ax^2 + bx + c = 0.
