(3x - 1)(3x - 4)
= (3x - 1)²
= (3x)² - 2 × 3x × 1 + 1²
= 9x² - 6x + 1
This is the standard form.
And if you want the solution too then refer the following:
9x² - 6x + 1
= 9x² - 3x - 3x + 1
= 3x(3x - 1) - 1(3x - 1)
= (3x - 1)(3x - 1)
Therefore x = 1/3 and 1/3
= (3x - 1)²
= (3x)² - 2 × 3x × 1 + 1²
= 9x² - 6x + 1
This is the standard form.
And if you want the solution too then refer the following:
9x² - 6x + 1
= 9x² - 3x - 3x + 1
= 3x(3x - 1) - 1(3x - 1)
= (3x - 1)(3x - 1)
Therefore x = 1/3 and 1/3
