We type the given equation like this (using the caret symbol ^ to show exponentiation): x^2 - 2x + 1 = 8y - 16 Your request for help is vague because you did not ask any questions of your own or make any statements about what you already know or tried. So, let's start with the following step: Complete the square in x. (If you need to refresh your memory on completing the square, click HERE or HERE for lessons.) We'll go from there. ?
