How To Prove Math A 2 B 2 C 2 Ab Ca Math Is Non Negative For All Values Of Math A B Math And Math C Quora  Multiply both sides with 2, we get 2 ( a2 b2 c2 – ab – bc – ca) = 0 ⇒ 2a2 2b2 2c2 – 2ab – 2bc – 2ca = 0 ⇒ (a2 – 2ab b2) (b2 – 2bc c2) (c2 – 2ca a2) = 0 ⇒ (a –b)2 (b – c)2 (c – a)2 = 0 Since the sum of square is zero then each term should be zero ⇒ (a –b)2 = 0, (b – c)2 = 0, (c – a)2 = 0 AB A'C BC I know it simplifies to A'C BC And I understand why, but I cannot figure out how to perform the simplification through the expression using the boolean algebra identities I was wondering if someone could show me the steps needed to do this Thank you in advance booleanalgebra Share Ab bc ca formula

According to the National Cancer Institute, nearly 50% of all women age 40 and older have dense breasts Like Joan, many women don't know whether they have dense breasts or what that means Knowing whether you have dense breasts is important because women with dense breasts have a higher risk of developing breast cancer, and often need Complex breast cysts account for approximately 5% of breast cysts that are present on screening mammograms So, usually a complex cyst of the breast indicates close followup and sometimes a biopsy There is a very very small chance that a complex breast cyst could be associated with malignant breast cancer, so they merit a higher degree of scrutinyThe categories are, (A) almost entirely fatty, (B) scattered fibroglandular density, heterogeneously dense, and (D) extremely dense On a mammogram, fatty and connective tissue shows up as a grey color and glandular tissue shows up as white – as do cancerous tumors The higher the breast tissue density – the hard...
