Question 61604: How do I finish this? x^2+8x-3=0
x^2+8x=3
x^2+8x+64/4=3/1+64/4=12/4+64/4=76/4
x^2+8x+64/4=76/4
(x+8/2)^2=76/4
x+8/2=+ or - the square root of 76/4........
I got stuck right here.

sqrt%2876%2F4%29 can be rewritten as sqrt%2876%29%2Fsqrt%284%29 and that can be rewritten as sqrt%284%2A19%29%2Fsqrt%284%29. That reduces to 2sqrt%2819%29%2F2, which reduces further to sqrt%2819%29.
