Quadratic equation calculator
Quadratic equation has the basic form: ax2+bx+c=0Enter 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:
2x2=72 2x2−72=0 2 ... prime number 0=0 72=23⋅32 GCD(2,0,72)=2=2 x2−36=0 x1,2=±36=±6 x1=6 x2=−6
Solution in text:
2x2-72=0 ... b=0; pure quadratic equationDiscriminant:
D = b2 - 4ac = 576
D > 0 ... The equation has two distinct real roots
x1 = 6
x2 = -6
P = {6; -6}
