    Solving the Quadratic Equation: y = x^2-8x+7

    Okay, thanks. :) How would I find the 'x =' in the equation? (y = x^2-8x+7) THANKS! :)

    Solving the Quadratic Equation: y = x^2-8x+7

    Thanks for all the help. :) On the question: Find the roots by using the quadratic equation. Would the answer be x = {7,14}? Thanks :)

    Solving the Quadratic Equation: y = x^2-8x+7

    The quadratic formula is: {-8 ± Sq Root (64 - 28)} ÷ 2 That means the discriminant is: 64 - 28 I hope that's right. Thanks! :blushing:

    Solving the Quadratic Equation: y = x^2-8x+7

    It probably is in my book, but I'm sick and my book was left in my locker as I thought I was going to school today. I'm looking it up on how to do it, although I can find examples I can't figure out how they change it. Thanks :) PS: The roots are x = {7,1} I believe?

    Solving the Quadratic Equation: y = x^2-8x+7

    Tryed myself, the discriminant is "x^2 - 8x"? The factor is: (x - 7)(x - 1) But are those the roots also? Not sure about #3. Thanks for the help! :) PS: Yes, this is in my Algebra II class.

    Solving the Quadratic Equation: y = x^2-8x+7

    I'm supposed to use this equation: y = x^2-8x+7 To solve the following questions: 1) What is the value of the discriminant? 2) Find the roots by factoring and solving. 3) Find the roots by using the quadratic equation. Can anyone give me some help? Thanks! :)
