使用Python实现求根公式 在数学中,求根公式(Quadratic Formula)是一种用于找到二次方程的根的方法。二次方程的标准形式为: [ ax^2 + bx + c = 0 ] 其中,a、b和c是常数,a不等于 0。根的计算过程可以由求根公式给出: [ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}{{2a}} ] 本文将逐步教你如何...
There always two solutions to a quadratic equation: x_1 & x_2. """x_1=(-b+(b**2-4*a*c)**(1/2))/(2*a)x_2=(-b-(b**2-4*a*c)**(1/2))/(2*a)returnx_1,x_2 对于单行docstrings,请将"""保持在同一行上 defquadratic(a,b,c,x):"""Use the quadratic formula"""x_1...

Note: The discriminant is the name given to the expression that appears under the square root (radical) sign in the quadratic formula. Test Data: The x value : 4 The y value : 0 The z value : -4 Expected Output: Two Solutions. Discriminant value is : 64.0 ...
The quickest way to define a complex number in Python is by typing its literal directly in the source code:Python >>> z = 3 + 2j Although this looks like an algebraic formula, the expression to the right of the equals sign is already a fixed value that needs no further evaluation. ...
