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:
(388128+4∗w)∗(w−1)=388128∗w 4w2−4w−388128=0 4=22 388128=25⋅3⋅13⋅311 GCD(4,4,388128)=22=4 w2−w−97032=0 a=1;b=−1;c=−97032 D=b2−4ac=12−4⋅1⋅(−97032)=388129 D>0 w1,2=2a−b±D=21±388129 w1,2=21±623 w1,2=0.5±311.5 w1=312 w2=−311 Factored form of the equation: (w−312)(w+311)=0
Solution in text:
4w2-4w-388128=0 ... quadratic equationDiscriminant:
D = b2 - 4ac = 6210064
D > 0 ... The equation has two distinct real roots
w1 = 312
w2 = -311
P = {312; -311}
