## anonymous 5 years ago need help: 2x^2+4x+1=0

1. anonymous

use the quadratic formula $(-b \pm \sqrt{b^2-4ax})/2a$ $(-4\pm\sqrt{4^2-4*2*1})/2*2$

2. anonymous

I don't get it

3. anonymous

its imposibble to use factorization(maybe) hence the quadratic formula

4. anonymous

How can we solve this eqaution to find the value of x?
