Question

Solve for b: 5b^2-5b+1=0

Answer 1

Use the Quadratic Equation.

Answer 2

\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] with
\[a=5,b=-5,c=1\]

Answer 3

I used that and the answer came out to be x=+/-square root 5/5. Does this sound crazy

Answer 4

No it dosn't.

Answer 5

Thx

Answer 6

Actually when you use the quadratic formula the answer you should get is: \[\ \frac{5\pm \sqrt{5}}{10} \]

Answer 7

Ok. So I don't need to reduce it any further?

Answer 8

no, you only reduce it further if all of the numbers there share a common factor say for instance if it was \[\ \frac{5\pm5\sqrt{5}}{10} \]

Answer 9

You know you have a common factor 5 that you can reduce

Answer 10

ok. THx

Answer 11

you're welcome
