Question

Mark solved the equation in the box, using the steps shown.8-√x = 108-√x = 10-√x = 2X = (-2)²X= 4Is the solution x = 4 correct? State yes or no, and justify your answer.O YESO NOO I DO NOT KNOW√√x = -2

Answer 1

Given:

`8-√(x)=10`

Required:

To check whether the solution x=4 is correct or wrong.

Step-by-step explanation:

Now put x=4 in to th original equation, we get

`\begin{gathered} 8-√(4)=10 \\ 8-2=10 \\ 6\\e10 \end{gathered}`

Therefore x=4 is not a solution.

Final Answer:

NO.

x=4 is not a solution for the given equation.
