Write the following in the form ${(x + a)}^{2} + b$

x^{2} + 9 x - 10

{(x + \frac{9}{2})}^{2} - \frac{121}{4}

x^{2} - 11 x - 10

{(x - \frac{11}{2})}^{2} - \frac{161}{4}

x^{2} - x + 3

{(x - \frac{1}{2})}^{2} + \frac{11}{4}

x^{2} - 2 x - 9

{(x - 1)}^{2} - 10

x^{2} - 11 x - 2

{(x - \frac{11}{2})}^{2} - \frac{129}{4}

x^{2} + 8 x + 5

{(x + 4)}^{2} - 11
