To factor out the expression, we look for terms with common factors. x² - x -42 = x(² - 1) - 42 The expression (² - 1) is equivalent to (S1U1P6S1P0 - 7), so we have: x(S1U1P6S1P0 - 7) - 42 = 0 The expression can now be factored as follows: (x-7)(S1U1P6S1P0) = 0 Thus, the solutions are x = 7 and x = -6, and the correct choice is C.
