Despejar la variable <br> 2x al cuadrado + 15= 113

Rudik [331]

Hola!

x = 7 , x = -7

Explicación:

Comienza restando 15 en cada lado:

$2x^{2} + 15 -15=113-15$

Usted obtiene:

$2x^{2} =98$

Ahora divide ambos lados por 2:

$\frac{2x^{2} }{2} =\frac{98}{2}$

Usted obtiene:

$x^{2} =49$

Como la ecuación está al cuadrado, tendrás que hacer:

$x=\sqrt{f(a)} , x=-\sqrt{f(a)}$

que te da: $x=\sqrt{49} , x =-\sqrt{49}$

Entonces:

$\sqrt{49}=7 , -\sqrt{49} = -7$
