Quadratic equation · Final answer
x = 3 or x = 2
How we solved it
- 1
x^2 - 5x + 6 = 0 - 2
Rearrange to standard form: 1x² + -5x + 6 = 0 - 3
Discriminant D = b² − 4ac = (-5)² − 4·(1)·(6) = 1 - 4
x = (−b ± √D) / 2a = (5 ± 1) / 2 - 5
x = 3 or x = 2
💡 Write in the form ax² + bx + c = 0 and apply the quadratic formula.
