Explanation Given Information: The provided polynomial equation is x 3 − 27 = 0 . Formula used: Zero product rule: An equation a b = 0 is true if and only if a = 0 or b = 0 , both A product is zero if and only if at least one factor is zero The value of x in the equation a x 2 + b x + c = 0 can be given by the quadratic formula, x = − b ± b 2 − 4 a c 2 a where a , b and c are real numbers with a ≠ 0 . Calculation: Consider the polynomial equation x 3 − 27 = 0 . First determine the single solution in this cubic equation x 3 − 27 = 0 Compare the equation x 3 − 27 = 0 with the standard cubic equation a x 3 + b x 2 + c x + d = 0 . a = 1 and d = − 27 Therefore, possible factor of 1 is x = ± 1 and 27 is x = ± 1 , x = ± 3 , x = ± 9 and x = ± 27 . First try x = 3 substitute in the provided polynomial equation x 3 − 27 = 0 , ( 3 ) 3 − 27 = ? 0 27 − 27 = ? 0 0=0 Which is true Therefore, x − 3 is a factor of the polynomial x 3 − 27 = 0 . In order to find other two values of x , divide x 3 − 27 = 0 by x − 3 , x − 3 x 2 + 3 x + 9 x 3 + 0 x 2 + 0 x − 27 x 3 − 3 x 2 _ 3 x 2 + 0 x 3 x 2 − 9 x _ <
