To express the solution to the equation \( 3x^2 + 7 = 10 \) in set notation, we will first solve the equation.
- Start by simplifying the equation:
\[ 3x^2 + 7 = 10 \]
- Subtract 7 from both sides:
\[ 3x^2 = 10 - 7 \]
\[ 3x^2 = 3 \]
- Divide both sides by 3:
\[ x^2 = 1 \]
- Take the square root of both sides:
\[ x = \pm 1 \]
This gives us two solutions: \( x = -1 \) and \( x = 1 \).
Now, we can express the solution set in set notation:
\[ { -1, 1 } \]
So the solution to the equation \( 3x^2 + 7 = 10 \) in set notation is \( { -1, 1 } \).
