CALCULO CON APLICACIONES

EJERCICIO 1.10

LINA CRUEL

Despejar x en las siguientes ecuaciones:

11. √(x+2) +  √((9*x)+7) == 7

 

var ('x') ecuacion1 = sqrt(x+2 ) + sqrt((9*x)+7 ) == 7 solve (ecuacion1,x)
[x == 2]

12. √(x+2) - √(x+7) = -1

var ('x') ecuacion2 = (sqrt( x + 2) - sqrt (x + 7)) == -1 solve (ecuacion2,x)
[sqrt(x + 7) == sqrt(x + 2) + 1]
13. ( √( x^2) - (3*x) + 4) = 2 
var ('x') ecuacion1 = (sqrt (x^2) - (3*x) + 4) == 2 solve (ecuacion1,x)
[x == 1/3*sqrt(x^2) + 2/3]

14. √( x+2)  + √(2*x + 5) = 5

var ('x') ecuacion4 = sqrt (x+2) + sqrt ((2*x)+5) == 5 solve (ecuacion4, x)
[sqrt(2*x + 5) == -sqrt(x + 2) + 5]
var('y') solve ((sqrt((2*y) + 5) == -sqrt(y+2) + 5),y)
[sqrt(2*y + 5) == -sqrt(y + 2) + 5]
var ('y') ecuacion5 = sqrt((2*y) + 5) == -sqrt(y+2) + 5 solve (ecuacion5, y)
[sqrt(2*y + 5) == -sqrt(y + 2) + 5]
