Answer 1

To express the values that make the equation \(3x^2 + 7 = 10\) true in set notation, we first solve the equation:

1. Subtract 7 from both sides: \[ 3x^2 = 10 - 7 \] \[ 3x^2 = 3 \]

2. Divide by 3: \[ x^2 = 1 \]

3. Take the square root of both sides: \[ x = \pm 1 \]

Thus, the solutions are \(x = -1\) and \(x = 1\).

In set notation, this can be expressed as: \[ {-1, 1} \]

So the correct answer is {-1, 1}.
