Answer:

x = 3 or x = 9

Explanation:

Solve for x over the real numbers:

(x - 9) (-2 x + 6) = 0

Split into two equations:

-2 x + 6 = 0 or x - 9 = 0

Factor constant terms from the left hand side:

-2 (x - 3) = 0 or x - 9 = 0

Divide both sides by -2:

x - 3 = 0 or x - 9 = 0

Add 3 to both sides:

x = 3 or x - 9 = 0

Add 9 to both sides:

Answer: x = 3 or x = 9
