$(x-1)^{2}=8$

Step-by-step explanation:

we have

$x^{2} -2x-7=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2} -2x=7$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} -2x+1=7+1$

$x^{2} -2x+1=8$

Rewrite as perfect squares

$(x-1)^{2}=8$

therefore

h=1, c=8
