If the roots of the quadratic equation \( x^2 - 7x + 12 = 0 \) are \( \alpha \) and \( \beta \), then the value of \( \alpha + \beta \) is:
Show Hint
For a quadratic equation, use Vieta's formulas to quickly find the sum and product of the roots. The sum is \( -\frac{b}{a} \), and the product is \( \frac{c}{a} \).
