Question

FACTORIZACION Y FORMULA GENERAL
z²+10z+16=0

Answer 1

Factorizacion
(z+8)(z+2) = 0
z +8 = 0 y z +2 = 0
z = -8 y z = -2

form gral

z = (-b +- raiz cuadrada (b^2 - 4ac)) / 2a
z = (-10 +- raiz (10^2 - 4 (1)(16))/ 2
z = (-10 +- raiz (100 - 64))/2
z = (-10 +- raiz (36))/2
z = (-10 +- 6)/2
z = -16/2 = -8 prim sol
z = -4/2 = -2 seg sol.
