2(x-2)^(2)-8=-4

How do i solve this quadratic equation with square roots

Find the equation of the line with slope =8 and passing through (6,53) write your equation in the form y=mx+b

What is the slope of the line shown below?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
