Can someone tell me the easiest code to find roots of a quadratic equation in c?

Question

C

Answer 1

If b**2-4ac is lesser than 0, what is the code and it's output

Answer 2

Thanks Peter

Answer 3

I want the code, sir!

Answer 4

Yeah, lab program

Answer 5

Anyway Thanks for your time,sir!

Answer 6

I can do it. But little confusing..

Answer 7

Somewhat, I understood the logic

Answer 8

Use this formulas:
X1 = (-b+sqrt(b**2-4*a*c))/(2*a)
X2 = (-b-sqrt(b**2-4*a*c))/(2*a)

Answer 9

Wow peter, good explanation it helps me too. I haven't learned this yet in school so i don't know so much

Answer 10

ohh maths i think i’m allergic but try this on lol

b2-4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots. If discriminant is greater than 0, the roots are real and different.

If the discriminant of a quadratic function is equal to zero, that function has exactly one real root and crosses the x-axis at a single point. To see this, we set b2 −4ac = 0 in the quadratic formula to get, is the x-coordinate of the vertex of a parabola?? something like that i feel old trying recall old maths. good luck hope the explanation helps the logic gates start working lol

Answer 11

Just do the input and output for this, you can do it alone, can't you?
Also isn't this a homework or sth?

Answer 12

And is it homework or what?

Answer 13

Have you done anything yourself and you want correcting it or you want me (anyone other) to code it from scratch?

And is it too hard to do input, and output?
