Completing the square
When solving x2+6x+8 by completing the square, what number is added to both sides to create a perfect square trinomial?
1 answer
To complete the square for the quadratic equation x^2 + 6x + 8, the number that needs to be added to both sides to create a perfect square trinomial is 9. This number is half the coefficient of the x-term (6), squared, which is (6/2)^2 = 3^2 = 9.
