Answer:
2
(3x - 2)
(3x - 1)
Explanation:
The initial expression is:
18x² - 18x + 4
First, all coefficients are even numbers, so we can factorize the expression as;
2(9x² - 9x + 2)
Now, we can rewrite the expression inside the parenthesis as:
2((3x)² - 3(3x) + 2)
So, we need to find two numbers that multiply to 2 and add to -3. These numbers are -2 and -1, so:
2(3x - 2)(3x - 1)
Therefore the answers are:
2
(3x - 2)
(3x - 1)
