Solve 3x^2+3x-3 = 0 Dividing each term by 3, x^2+x-1 = 0 Method 1. Completing the square => (x+1/2)^2 = 1+1/4 = 5/4 x = -(1/2) ± √(5)/2 <==Answer Method 2. Using quadratic formula x = (-1±√(1+4))/2 = -(1/2) ± √(5)/2<==Same answer 10/24/2013 | Robert J. Comment Comments How do I write this in a answer from its not accepting it 10/24/2013 | David from Melbourne, FL If it's computer-based, sometimes the software wants two separate answers, separated by commas. Try: (-1+√5)/2, (-1 - √5)/2 or -1 + √5 , -1 - √5 --------- -------- 2 2 10/24/2013 | Jason S. Comment
