The form ax2+bx+c=0 is called the standard form of the quadratic equation.

Notice that standard form is not unique.

For example, x2−x+1=0 can be written as the equivalent equation −x2+x−1=0.

Also, 4x2−2x+2=0 can be written as the equivalent equation 2x2−x+1=0.

In this exercise, all answers are reported in the form ax2+bx+c=0 with a>0,

and where the greatest common factor of all nonzero coefficients is 1.
