3x2 - 6x - 7 = 0
x = (-b+-√b2-4ac) / 2a
x = (6+-√-62-4*3*-7) / 2*3
x = (6+-√36+84) / 6
x = (6+-√120) / 6
x = (6+-2√30) / 6
x = 2(3+-√30) / 6
x = (3+-√30) / 3
x = 1 +- (√30 / 3) Answer

This is in python language Algebra: solve quadratic equations) The two roots of a quadratic equation, for example, 0, can be obtained using the following fomula: b 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. Write a program that prompts the user to enter values for a, b, and cand...
