Our calculator can factor quadratic equations and provide the roots, making it easy to solve the equation.

Vertex Form:

The vertex form of a quadratic equation is y = a(x - h)2 + k, where (h, k) is the vertex of the parabola represented by the equation.

Real and complex roots

Quadratic equations can have real roots, complex roots, or a mixture of both. Our online calculator is equipped to handle all these cases and provide accurate solutions:

Real Roots:

Real roots are roots that are real numbers. They can be either rational (expressible as a fraction of two integers) or irrational (not expressible as a fraction of two integers). For example, the equation x2 - 4x + 1 = 0 has two real roots: 2 and 2. Our calculator can solve quadratic equations with real roots and provide the exact values of the roots.

Complex Roots:

Complex roots are roots that are not real numbers. They are numbers that have both a real part and an imaginary part. The imaginary part is a multiple of the imaginary unit i, where i2 = -1. For example, the equation x2 + 2x + 2 = 0 has two complex roots: -1 + i and -1 - i. Our calculator can solve quadratic equations with complex roots and provide the exact values of the roots in the form of a + bi, where a and b are real numbers.

Mixed Roots:

It is possible for a quadratic equation to have both real and complex roots. For example, the equation x2 - 2x + 2 = 0 has one real root (1) and one complex root (1 + i). Our calculator can handle these cases and provide the complete set of roots, including both the real and complex roots.
