The answer is : x^2 + 5x - 5 = 0 add five to both sides x^2 + 5x = 5 Complete the square x^2 + 5x + (5/2)^2 = 5 + (5/2)^2 (x + 5/2)^2 = 5 + 25/4 Take the square root of both sides x + 5/2 = sqrt(5 + 25/4) x = sqrt(5 + 25/4) - 5/2 x = sqrt(20/4 + 25/4) - 5/2 x = sqrt(45/4) - 5/2 x = 0.854101966

X=3/5.....add the 5 to the 0. Then subtract the 2 from the 5 to get 5x=3. Then divide 3 and 5x to get your answer.
