quadratic

[Husain111]

I am using Polynomial Roots VI to solve simple quadratic equation but alwas ge the wrong answer. Let us have simple proplem 2*X^2+2*X+0=0, the roots of thos are -1,0 but the VI gives different roots.

Check your array, it is currently [0, 2, 2, 4]

Yes.  You are asking the Root Finder to find the roots of a cubic (just because you can't "see" the fourth coefficient in your Constant Array doesn't mean it isn't there ...)

BS

Well stoppted. It was a studipd mistake from my side.

Don't beat yourself up over it.  That's why it's always important to have  a second set of eyes to look at the problem.  🙂
