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.

6∗(x−10)+6∗x=(x−10)∗x −x2+22x−60=0 x2−22x+60=0 a=1;b=−22;c=60 D=b2−4ac=222−4⋅1⋅60=244 D>0 x1,2=2a−b±D=222±244=222±261 x1,2=11±7.81025 x1=18.810249676 x2=3.189750324 Factored form of the equation: (x−18.810249676)(x−3.189750324)=0
Solution in text:
-x2+22x-60=0 ... quadratic equationDiscriminant:
D = b2 - 4ac = 244
D > 0 ... The equation has two distinct real roots
x1 = 18.8102497
x2 = 3.1897503
P = {18.8102497; 3.1897503}
