To resolve the expression ^4 - ^3 + - 1 into factors. Step 1: Let x = . Substitute x into the expression. x^4 - x^3 + x - 1 Step 2: Group the terms. (x^4 - x^3) + (x - 1) Step 3: Factor out the common term from the first group. x^3(x - 1) + (x - 1) Step 4: Factor out the common binomial factor (x - 1). (x - 1)(x^3 + 1) Step 5: Recognize that x^3 + 1 is a sum of cubes, which can be factored using the formula a^3 + b^3 = (a+b)(a^2 - ab + b^2). Here, a=x and b=1. (x - 1)(x + 1)(x^2 - x + 1) Step 6: Substitute back for x. ( - 1)( + 1)(^2 - + 1) The factored expression is: ( - 1)( + 1)(^2 - + 1)
