OK here is a stumper... Solve for b: 5b^2-5b+1=0

OpenStudy (anonymous):

Solve for b: $5b ^{2}-5b+1$

OpenStudy (anonymous):

$5+\sqrt{5}/10, 5-\sqrt{5}/10$

OpenStudy (anonymous):

1+sqrt(5)/2 0r 1-sqrt(5)/2

OpenStudy (anonymous):

by using quadratic formula $\frac{-b \pm \sqrt{b^2-4ac}}{2a}$ where a=5,b=-5 and c=1 plug the values into the formula $\frac{-(-5)\pm \sqrt{(-5)^2-4(5)(1)}}{2(5)}$ $\frac{5\pm \sqrt{25-20}}{10}$ $\frac{5\pm \sqrt{5}}{10}$ $\frac{5+\sqrt{5}}{10},\frac{5-\sqrt{5}}{10}$

But the simplified answer is what I gave
