Resolver:
16pq^2x^2 - 312pq^2X - 160pq^2

Answer 1

Respuesta:

Explicación paso a paso:

(16pq^2)x^2 - (312pq^2)x - 160pq^2 = 0

Dividimos la igualdad entre (8pq^2):

(16pq^2)x^2/(8pq^2) - (312pq^2)x /(8pq^2) - 160(pq^2)/(8pq^2) = 0

2x^2 - 39x - 20 = 0

Factorizamos por el Método del Aspa Simple:

x - 20

2x + 1

(x)•(2x) = 2x^2

(2x)•(- 20) + (x)•(+1) =

- 40x + x = - 39x

(- 20)•(+1) = - 20

(x - 20) (2x + 1) = 0

Igualamos cada factor a cero:

x - 20 = 0

x = 20

x1= 20

2x+ 1 = 0

2x = - 1

x = - 1/2

x2 = - 1/2

C.S. = {20, - 1/2}
