Question

Which technique is most appropriate to solve this equation?

Answer 1

Answer:

Square root property

Step-by-step explanation:

The given equation is :

$x^2+6=31$

We need to write the most appropriated technique to solve the above equation.

Subtracting both sides of the above equation by 6 such that,

$x^2+6-6=31-6\\\\x^2=25$

Now taking square root on both sides we get :

$x=\sqrt{25}$

The square root property is used here, such that the value of x is :

$x=\pm 5$
