• Ways to Solve Quadratic Equations. The most popular way to solve quadratic equations is to use a quadratic formula. This formula is: -b ±√b 2 – 4ac/2a. To solve, you will need to find the values of a, b, and c using the equation you are provided. Another way to solve quadratic equations is to use the factoring method.
As you can see, in order to solve the equation the cmath module must be imported, and equation is solved by using multiplication, division, and the cmath.sqrt method (which can be used to find the square root of a number). The printed text can be customized to say anything you like.
  • Your input: solve the quadratic equation x 2 − 14 x + 45 = 0 by using quadratic formula. The standard quadratic equation has the form a x 2 + b x + c = 0. In our case, a = 1, b = − 14, c = 45. Now, find the discriminant using the formula D = b 2 − 4 a c: D = ( − 14) 2 − 4 ⋅ 1 ⋅ 45 = 16.
  • Key Strategy in Solving Quadratic Equations using the Square Root Method. The general approach is to collect all {x^2} terms on one side of the equation while keeping the constants to the opposite side. After doing so, the next obvious step is to take the square roots of both sides to solve for the value of x.Always attach the \pm symbol when you get the square root of the constant.
  • Solving Quadratic Equations By Square Root Method Consider the equation x2 = a2, which we now solve: x2 = a2 x2 – a2 = 0 (x – a)(x + a) = 0 x – a = 0 x + a = 0 x = a x = –a x = ±a Because we solve certain equations the same way all the time, we can now take a shortcut. Square Root Rule: You may take the square root of both sides of an ...

First of all, the same method "completing the square" works for the quadratic equation (1) with complex coefficients also. Therefore, the same quadratic formula is valid for the roots of the quadratic equations (1) with complex coefficients (7) or, in the other form, (8) where (9) is the discriminant.
