Cara menggunakan quadratic program python

Given a quadratic equation the task is solve the equation or find out the roots of the equation. Standard form of quadratic equation is –

ax2 + bx + c where, a, b, and c are coefficient and real numbers and also a ≠ 0. If a is equal to 0 that equation is not valid quadratic equation.

Examples:

Input :a = 1, b = 2, c = 1 Output : Roots are real and same -1.0 Input :a = 2, b = 2, c = 1 Output : Roots are complex -0.5 + i 2.0 -0.5 - i 2.0 Input :a = 1, b = 10, c = -24 Output : Roots are real and different 2.0 -12.0

Method 1: Using the direct formula

Using the below quadratic formula we can find the root of the quadratic equation.

There are following important cases.

If b*b < 4*a*c, then roots are complex (not real). For example roots of x2 + x + 1, roots are -0.5 + i1.73205 and -0.5 - i1.73205 If b*b == 4*a*c, then roots are real and both roots are same. For example, roots of x2 - 2x + 1 are 1 and 1 If b*b > 4*a*c, then roots are real and different. For example, roots of x2 - 7x - 12 are 3 and 4

For example, roots of x2 - 2x + 1 are 1 and 1 If b*b > 4*a*c, then roots are real and different. For example, roots of x2 - 7x - 12 are 3 and 40 If b*b < 4*a*c, then roots are complex (not real). For example roots of x2 + x + 1, roots are -0.5 + i1.73205 and -0.5 - i1.73205 If b*b == 4*a*c, then roots are real and both roots are same. For example, roots of x2 - 2x + 1 are 1 and 1 If b*b > 4*a*c, then roots are real and different. For example, roots of x2 - 7x - 12 are 3 and 401
