-- Factor the left side of the equation.
-- Set one factor equal to zero, and solve it for 'x'. That gives you
one solution to the equation.
-- Set the other factor to zero, and solve it for 'x'. That gives you
the other solution to the equation.
-- If you don't get x=2 and x=-8/3 then repeat the previous steps,
because you made a mistake the first time.

It can be solved by using the quadratic equation formula.
Factor it. (x - 8)(x - 2) x = 2, 8
zero
x2-2x+1 = 0 (x-1)(x-1) = 0 x = 1 and also x = 1
It can't be factored because its discriminant is less than zero.
