Question

considerando a equação 10ײ—1000=0,duas raizes e distintas,×' e ×", podem ser encontradas.determine (×')²+(×")².

Answer 1

$10x^2-1000=0\\\\10x^2=0+1000\\\\10x^2=1000\\\\x^2=\frac{1000}{10}\\\\x^2=100\\\\x=\pm\sqrt{10}\\\\S=\{-10,\ 10\}$

Sendo x' = -10 e x'' = 10, temos que:

(x')² + (x'')² = (-10)² + (10)² = 100 + 100 = 200

(x')² + (x'')² = 200
