¿Cómo usar?
- La ecuación:
-
Ecuación x^3-x^2-x-1=0
-
Ecuación 3x-2(3x+4)=10
-
Ecuación 12-4(x-3)=39-9x
-
Ecuación 0,2x+2,7=1,4-1,1x
- Expresar {x} en función de y en la ecuación:
- -11*x-3*y=14
- 2*x-15*y=-1

- 6*x+9*y=-9
-
Expresiones idénticas
- dos x- uno /(x- cinco)-(3x+ dos)/x+ cuatro =(14x+ once)/(x^2-x- veinte)
- 2x menos 1 dividir por (x menos 5) menos (3x más 2) dividir por x más 4 es igual a (14x más 11) dividir por (x al cuadrado menos x menos 20)
- dos x menos uno dividir por (x menos cinco) menos (3x más dos) dividir por x más cuatro es igual a (14x más once) dividir por (x al cuadrado menos x menos veinte)
- 2x-1/(x-5)-(3x+2)/x+4=(14x+11)/(x2-x-20)
- 2x-1/x-5-3x+2/x+4=14x+11/x2-x-20
- 2x-1/(x-5)-(3x+2)/x+4=(14x+11)/(x²-x-20)
- 2x-1/(x-5)-(3x+2)/x+4=(14x+11)/(x en el grado 2-x-20)
- 2x-1/x-5-3x+2/x+4=14x+11/x^2-x-20
- 2x-1 dividir por (x-5)-(3x+2) dividir por x+4=(14x+11) dividir por (x^2-x-20)
-
Expresiones semejantes
- 2x-1/(x-5)+(3x+2)/x+4=(14x+11)/(x^2-x-20)
- 2x-1/(x+5)-(3x+2)/x+4=(14x+11)/(x^2-x-20)
- 2x-1/(x-5)-(3x+2)/x+4=(14x+11)/(x^2-x+20)

- 2x-1/(x-5)-(3x+2)/x+4=(14x-11)/(x^2-x-20)
- 2x+1/(x-5)-(3x+2)/x+4=(14x+11)/(x^2-x-20)
- 2x-1/(x-5)-(3x+2)/x-4=(14x+11)/(x^2-x-20)
- 2*x-1/x-5-3*x+2/x+4=14*x+11/x^2-x-20
- 2x-1/(x-5)-(3x-2)/x+4=(14x+11)/(x^2-x-20)

1 3*x + 2 14*x + 11
2*x - ----- - ------- + 4 = -----------
x - 5 x 2
x - x - 20
$$\left(\left(2 x - \frac{1}{x - 5}\right) - \frac{3 x + 2}{x}\right) + 4 = \frac{14 x + 11}{\left(x^{2} - x\right) - 20}$$
