Question

15/x - (11x +5)/x^2 = -1

Answer 1

Explicación paso a paso:

15/x - (11x + 5)/x^2 = -1

Multiplicamos todo por "x^2"

x^2(15/x - (11x+5)/x^2 = x^2(-1)

15x - (11x+5) = -x^2

15x - 11x - 5 = -x^2

4x - 5 = - x^2

x^2 + 4x - 5 = 0

x 5

x -1

Entonces:

x + 5 = 0

x = -5

x - 1 = 0

x = 1

Rpta: 1 y -5
