You must add (17n + 144).
X2 - 8X = 3halve the linear term (- 8 ), square it and add it to both sidesX2 - 8X + 16 = 3 + 16factor left, gather terms right(X - 4)2 = 19(X - 4)2 - 19 = 0-------------------------(4, - 19)----------------the vertex16 is the number that needed to be added to both sides to complete the square
If: x^2 +18x = 29 Then completing the square: (x+9)^2 -81 = 29 or (x+9)^2 = 110
49 x2 + 14x = -7 x2 + 14x + 49 = 42 (x + 7)2 = 42 x = -7 ± √42
just take the coefficient of the "x" term and half it then square it...11 / 2 = 5.55.52 = 30.25The answer to your question is 30.25.

The idea is to take half the linear part (12, in this case), then square it. The constant part must be equal to this result.
Put in the - or + values for 4x and 7 is the first step in finding the number needed
square root -5 minus 14 or - square root -5 minus 14
