When you add or subtract algebraic expressions, you combine like terms by adding coefficients in front of the variables. Your equation doesn't have like terms so it's already in simplest forms. But if you were to factor it, it would be (ac-1)^2
a²c² - 2ac + 1
Factor using FOIL
(ac)(ac) = a²c², so use ac and ac for the first terms.
(ac ... )(ac ... )
(1)(1) = 1, so use 1 and 1 for the last terms.
(ac ... 1)(ac ...1)
The outer and inner products are ac and ac which can make - 2ac if the signs are both negative.
a²c² - 2ac + 1 = (ac - 1)(ac - 1) = (ac - 1)²
problem? I assume you mean factor
(ac-1)^2
