About this tool
Enter the coefficients a, b and c of ax² + bx + c = 0. The solver finds both roots using the quadratic formula, tells you the discriminant and shows the vertex and axis of symmetry. If the discriminant is negative, the roots are shown as complex numbers.
When to use it
Solve ax² + bx + c = 0 and see the roots, discriminant and vertex.
Tips
If the discriminant is negative, there are no real roots.

Mfano uliotatuliwa
With the boxes at their starting values (a (coefficient of x²): 1; b (coefficient of x): -3; c (constant): 2), the tool shows: Discriminant: 1; Vertex: (1.5, -0.25); Axis of symmetry: x = 1.5; Root x₂: 1; Root x₁: 2. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.
Vidokezo vya matokeo bora
Angalia kila kisanduku kabla ya kuamini matokeo, kwa sababu nambari moja isiyo sahihi hubadilisha jibu zima. Tumia nambari kamili kutoka kwenye hati ya mshahara, ankara, cheti au mkataba na uandike tarehe uliyohesabu. Viwango, vizingiti na sheria hubadilika mara kwa mara, kwa hivyo kwa kodi, ada na masuala ya kisheria chukulia matokeo kuwa makadirio na uyathibitishe na chanzo rasmi kilichotajwa kwenye ukurasa huu. Unaweza kujaribu hali nyingi unavyotaka; hakuna kinachohifadhiwa wala kutumwa na kupakia upya ukurasa husafisha visanduku.

Maswali yanayoulizwa mara kwa mara
What is the discriminant?
b² − 4ac. If it is positive there are two real roots, if zero one repeated root, if negative two complex roots.
What if a is 0?
Then it is not a quadratic equation. It becomes a straight line, so a must not be zero.
What is the discriminant?
b² − 4ac. It tells how many real roots exist.
What if a is zero?
Then it is not quadratic.
