Quadratic equation calculator

Quadratic equation has the basic form:

a x^{2} + b x + c = 0

Enter the quadratic equation's coefficients a, b, and c of its basic standardized form. A solution of quadratic equations is usually two different real or complex roots or one double root — the calculation using the discriminant.

Calculation:

676 x = x^{2} + 31 2^{2} - x^{2} + 676 x - 97344 = 0 x^{2} - 676 x + 97344 = 0 a = 1; b = - 676; c = 97344 D = b^{2} - 4 a c = 67 6^{2} - 4 \cdot 1 \cdot 97344 = 67600 D > 0 x_{1, 2} = \frac{- b \pm D}{2 a} = \frac{6 7 6 \pm 6 7 6 0 0}{2} x_{1, 2} = \frac{6 7 6 \pm 2 6 0}{2} x_{1, 2} = 338 \pm 130 x_{1} = 468 x_{2} = 208 Factored form of the equation: (x - 468) (x - 208) = 0

Solution in text:

-x²+676x-97344=0 ... quadratic equation

Discriminant:
D = b² - 4ac = 67600
D > 0 ... The equation has two distinct real roots

x₁ = 468
x₂ = 208

P = {468; 208}
