Solve the equation, and check the solutions √(x+6)=3.

posledela

Answer:

The solution is $x = 3$

Step-by-step explanation:

We have the following equation:

$\sqrt{x+6} = 3$

Elevating both sides to 2, we can isolate x

$\sqrt{x+6}^{2} = 3^{2}$

$x + 6 = 9$

$x = 9 - 6$

$x = 3$

Checking

$\sqrt{x+6} = \sqrt{3+6} = \sqrt{9} = 3$
