I love to code. I believe everything is programmed in a certain way to make it work. From human brains to every single command in the machines.

There are some people who may not exactly like doing things that are related to math, but if you would like to learn how to solve quadratic equations, these are just a few of the things that you can do:

• You would need to put the equation into a different form. The form will be ax2 + bx = −C

• A should be equal to 1; otherwise, you will not be able to proceed.

• You would need to use the value of b to complete the equation.

• Now that you have both sides of the equation, you need to get the square root.

• You can now solve based on the equation that you have.

It may be confusing in the beginning, but the more that you practice, the more that you will understand how this should be done.

• The first step is to move all of the terms to the left-hand side of the equation and ensure that the a term is positive if it is not multiply through by -1

• Move the term c to the right-hand side of the equation

• Divide through by the coefficient of x2 or the a, in case the x2 has no coefficient, or it has a coefficient of 1 you can skip this step

• Pick the term b, halve it after that square it and add the result to both sides of the equation.

• After you have summed up the square of half of b to both sides then simplify the two sides of the equation

• Factor out the term on the left-hand side to get something like (x-2)(x-2) or(x-2)2 and add up the terms on the right side

• Determine the square roots on both sides of the equation then simplify the radical.
