Contoh: x² + 8x + 6 = 0 => (x + 4)(x + 4)
(1) x² + 2x + 1 = 0 => (x + 1)(x + 1)
(2) x² + 18x + 81 = 0 => (x + 9)(x + 9)
(3) x² – x – 2 = 0 => (x + 1)(x – 2)
(4) x² – 5x + 6 = 0 => (x – 2)(x – 3)
(5) x² – x – 6 = 0 => (x + 2)(x – 3)
(6) x² + x – 42 = 0 => (x – 6)(x + 7)
(7) x² – 4x + 4 = 0 => (x – 2)(x – 2)
(8) 2x² – x – 1 = 0 => (2x + 1)(x – 1)
(9) 3x² – 4x – 4 = 0 => (3x + 2)(x – 2)
(10) 5x² + 13x – 6 = 0 => (5x – 2)(x + 3)
(11) x² – 16 = 0 => (x – 4)(x + 4)
(12) 4x² – 9 = 0 => (2x – 3)(2x + 3)
(13) x² – 1 = 0 => (x + 1)(x – 1)
(14) x² + 13x + 42 = 0 => (x + 6)(x + 7)
(15) 2x² – 9x + 7 = 0 => (2x – 7)(x – 1)
