x² - 2x -35=0 solve each equation by competing the square
:
x^2 - 2x + ____ = 35
Find the value that will complete the square, half the coefficient of x, squared
it's 1, add to both sides
x^2 - 2x + 1 = 35 + 1
(x - 1)^2 = 36
Find the square root of both sides
x - 1 = +/- sqrt%2836%29
Two solutions
x = 1 + 6
x = 7
and
x = 1 - 6
x = -5
