Data & Statistics
| Equation | Possible Zeros |
|---|---|
| x² – 5x + 6 = 0 | 2, 3 |
| 2x² – 7x + 3 = 0 | 1, 3/2 |
Expert Tips
- Always check if the discriminant (b² – 4ac) is greater than, equal to, or less than zero to determine the number of possible zeros.
- Remember, possible zeros are not always real roots. They can also be complex numbers.
Interactive FAQ
What if the discriminant is negative?
If the discriminant is negative, the equation has no real roots, only complex roots.
Can I find possible zeros of a linear equation?
No, the formula for finding possible zeros only works for quadratic equations (ax² + bx + c = 0).
