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:
a2−pow((1−25/100)a,2)=28 0.4375a2−28=0 a1,2=±28/0.4375=±8 a1=8 a2=−8
Solution in text:
0.4375a2-28=0 ... b=0; pure quadratic equationDiscriminant:
D = b2 - 4ac = 49
D > 0 ... The equation has two distinct real roots
a1 = 8
a2 = -8
P = {8; -8}
