Quadratic Equation Solver vs Critical Points Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Quadratic Equation Solver
Finds real roots of any quadratic equation ax² + bx + c = 0 using the quadratic formula. Use it whenever you need to factor a parabola, find x-intercepts, or solve physics and engineering problems involving squared variables.
- Answers
- Solution x₁
- Inputs
- Coefficient a, Coefficient b, Coefficient c
Critical Points Calculator
Finds the x-coordinate of the critical point (vertex) of a quadratic function ax² + bx + c by setting its derivative equal to zero. Use it to locate the maximum or minimum of any parabola instantly.
- Answers
- Critical Point x-value
- Inputs
- x² Coefficient (a), x Coefficient (b)
