(x2 - 4), (x2 - 5x - 6), (x2 + x - 6)
ആശയം:
ഉസാഘ: ഓരോ സംഖ്യകളിലെയും പൊതു അഭാജ്യഘടകത്തിന്റെയും ഏറ്റവും ചെറിയ ഘാതത്തിന്റെ ഗുണനം.
ലസാഗു: സംഖ്യകളിൽ ഉൾപ്പെട്ടിരിക്കുന്ന ഓരോ അഭാജ്യഘടകത്തിന്റെയും ഏറ്റവും വലിയ ഘാതത്തിന്റെ ഉൽപ്പന്നം.
കണക്കുകൂട്ടൽ:
നമുക്കറിയാം, a2 - b2 = (a + b)(a - b)
⇒ x2 - 4 = (x + 2)(x - 2)×1
x2 - 5x - 6 = x2 - 6x + x - 6
⇒ x2 - 5x - 6 = (x - 6)(x + 1)×1
x2 + x - 6 = x2 + 3x - 2x - 6
⇒ x2 + x - 6 = (x + 3)(x - 2)×1
ഉസാഘ ഓരോ സംഖ്യകളിലെയും പൊതു അഭാജ്യഘടകത്തിന്റെയും ഏറ്റവും ചെറിയ ഘാതത്തിന്റെ ഗുണനം ആയതിനാൽ,
ഇവിടെ പൊതുഘടകമില്ല എന്ന് വ്യക്തമാണ്.
∴ ഉസാഘ = 1
Mistake Points(x - 2), x2 - 5x - 6 ന്റെ ഘടകമല്ല,
x = 2 ആണെങ്കിൽ,
(2)2 - 5 × 2 - 6 = 4 - 10 - 6 ≠ 0
