Homework Help: algebra

Posted by kate on Sunday, November 18, 2007 at 11:39am.

can someone tell me if i did the problem correct (solve by completing the square) 4x^2+2x-3=0
x^2+(1/2)=3/4
x^2+(1/2)+(1/4)^2=3/4+(1/4)^2
(x+1/4)^2=13/16
x+1/4=+-sqrt 13/16
x+1/4=+-sqrt 13/4
x=-1/4+-sqrt 13/4
x=-1+-sqrt 13/4
