Question

Ayudenme porfavor es mi examen trabajo

Answer 1

Respuesta:

u= 1

Explicación paso a paso:

(u+2) / (3.u-1) + 1 = (6-u) / (u+1)

[(u+2) + (3.u - 1) ] / (3.u - 1) = (6-u) / (u+1)

(4.u +1) / (3.u - 1) = (6-u) / (u+1)

(4.u+1) . (u+1) = (6-u) . (3.u-1)

4.u^2 + 5.u + 1 = 18.u - 6 - 3.u^2 + u

7.u^2 - 14.u + 7 = 0

7. (u^2 - 2.u + 1) = 0

u^2 - 2.u + 1 = 0

u -1

u -1

(u-1) . (u-1) = 0

u= 1
