YES!! But tell me what are the values of 'a, b, c, m, r' first. :P

Yes, I can, but I will not! This is a simple 2nd degree equation: why don't you do your homework by yourself?

Hi
I am assuming the programming language as C#
You can use Math.Pow() Function to accomplish this in C#. You can refer [this.]

You can convert the equation to result with

Math.Pow((x - a), 2) + Math.Pow((mx + c - b), 2) = Math.Pow(r,2);

:) But your equation seems like it should be ended with "Hence Proof"

Math.Sqrt compute the square root, then Math.Sqrt(x - a) is not the same than Math.Pow((x - a), 2)

Solution 2

As you probably know, with a bit of manipulation, your 'formula' maybe written

A x^2 + B x + C=0

That is a canonical quadratic equation[^], having a straightforward solution.
