Answer 1

Step-by-step explanation:

Signs and symptoms are abnormalities that can indicate a potential medical condition. Whereas a symptom is subjective, that is, apparent only to the patient (for example back pain or fatigue), a sign is any objective evidence of a disease that can be observed by others (for example a skin rash or lump).

Answer 2

Answer:

9x4−3x2+1

=9x4+1−3x2

=(3x2)2+(1)2+2(3x2)(1)−2(3x2)(1)−3x2

=(3x2+1)2−9x2∵a2+b2+2ab=(a+b)2

=(3x2+1)2−(3x)2

=(3x2+1−3x)(3x2+1+3x)∵a2−b2=(a−b)(a+b)

=(3x2−3x+1)(3x2+3x+1)
