Question

if a+b+c=5 and ab+bc+ac=12 find a^+b^+c^

Answer 1

Step-by-step explanation:

GIVEN,

a + b + c = 5

⇒(a + b + c)² = 5²

⇒a² + b² + c² + 2ab + 2bc + 2ca = 25

⇒a² + b² + c² + 2(ab + bc + ca) = 25

⇒a² + b² + c² + 2 × 12 = 25

⇒a² + b² + c² + 24. = 25

⇒a² + b² + c² = 25 - 24

⇒a² + b² + c² = 1
