Desenvolvimento Alg�brico
[ ( 1 )x² + ( -2 )x + ( -517 ) ] = 0
a = ( 1 );
b = ( -2 );
c = ( -517 );
Calculando Δ
Δ = b² - 4.a.c
Δ = {( -2 )² - [ 4.( 1 ).( -517 ) ]}
Δ = 2072
C�lculo das Ra�zes
X' = {-b + ²√Δ} / {2.a}
X' = { 2 + ²√( 2072 } / { 2.( 1 )}
X' = ( 23,75961335 );
X" = {-b - ²√Δ} / {2.a}
X" = { 2 - ²√( 2072 )} / { 2.( 1 )}
X" = ( -21,75961335 );
