To solve for x, first, we add 3 to the given equation:

\begin{gathered} 2(x+5)^2-3+3=44+3, \\ 2(x+5)^2=47. \end{gathered}

Dividing by 2, we get:

(x+5)^2=\frac{47}{2}.

Therefore:

x+5=\pm\sqrt{\frac{47}{2}}.

Finally, subtracting 5 we get:

x=\pm\sqrt{\frac{47}{2}}-5.

Answer:

x=\operatorname{\pm}\sqrt{\frac{47}{2}}-5.

X=32

Explanation:
When you change sides, if in the left side you are multiplying, when you transfer it to right side you divide. Same thing should be done for addition subtraction.

So /-4 was division and negative number

When we transfered it, it became positive multiplication number
