Question

Which of the following is true about the solution(s) to the equation:

Answer 1

Given:

`x=\sqrt[]{2x+3}`

To find the solutions:

Squaring on both sides we get,

`\begin{gathered} x^2=2x+3 \\ x^2-2x-3=0 \\ (x+1)(x-3)=0 \\ x=-1,\text{ 3} \end{gathered}`

Hence, x=3 and x= -1 are the solutions.

Therefore, the correct option is the second one.
