To solve the equation \(x^2 + 2x = 3\), we first rewrite it in standard form:
\[ x^2 + 2x - 3 = 0 \]
Next, we can factor the quadratic equation:
\[ (x + 3)(x - 1) = 0 \]
Setting each factor equal to zero gives us two solutions:
- \(x + 3 = 0\) \(\Rightarrow\) \(x = -3\)
- \(x - 1 = 0\) \(\Rightarrow\) \(x = 1\)
So the solutions to the equation \(x^2 + 2x = 3\) are:
\[ x = -3 \quad \text{and} \quad x = 1 \]
Based on the provided responses, the correct answer is:
x = -3, 1 (x equals negative 3 comma 1).
