Long Factoring of y = -1/9(7x^2 - 56x + 58)

[helpsalot]

I can't seem to figure this out for myself. Could someone show me the steps for long factoring this equation.

y=-1/9(7x^2-56x+58)

Any help would be appreciated.
Thanks.

The polynomial inside the parentheses is not factorable. Its discriminant is not a perfect square.

If you're trying to solve for x when y is 0, you could complete the square. :cool:

Prehaps you could help me with the root of my problem then which is converting

y=7/9(x-4)^2+6

To factored form.
Thanks for your help.

We'll be glad to help, but we'll first need to see what you've tried and where you're getting stuck. You multiplied out the square, simplified, and... then what?

Note: This second polynomial you've posted, like the first, does not actually appear to be factorable in the rationals. Are you sure you've posted the function correctly? Thank you!
