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:
c2−9=0 c2−9=0 c1,2=±9=±3 c1=3 c2=−3
Solution in text:
c2-9=0 ... b=0; pure quadratic equationDiscriminant:
D = b2 - 4ac = 36
D > 0 ... The equation has two distinct real roots
c1 = 3
c2 = -3
P = {3; -3}
