Question

Quadratic Equation help:
if x = -b ± √b^2 - 4ac /2
would the -6 in the equation 4x^2 - 6x + 1 = 0
be -6 or would it be 6 for -b?

a = 4, b = -6, c = 1

Answer 1

So I'm using the wrong formula?

Answer 2

Yes. Just like you have it.

Answer 3

Okay, but I don't understand if my eqaution is supossed to be either
x = -6 ± √-6^2 - 4(4)(6) /2
or
x = 6 ± √-6^2 - 4(4)(6) /2

Answer 4

over 2a, i mean.

Answer 5

\[x=\frac{6\pm \sqrt{36-4(4)(1)}}{8}\]

Answer 6

Oh okay, thank you!
