To solve for x, you must use the square root and remember to split the answers into 2:
\((x+3)^2=7\) | Take the square root of both sides |
\(x+3=\sqrt{7}\) | However, remember that the absolute value equation splits your answer into the negative and positive answer |
\(x+3=\pm\sqrt{7}\) | Subtract 3 on both sides |
\(x=\pm\sqrt{7}-3\) | |
\(x\approx-0.35425\hspace{1mm}\text{and}\hspace{1mm}x\approx-5.64575\) | Here are your answers rounded, but you want to keep your answer as it is above because that is the exact value. |
