Use the quadratic formula to solve x^2-2x+2=0

Helen [10]

The quadratic formula is...
$\frac{-b (+/-)\sqrt{b^2-4ac}}{2a}$
your a will be in front of your x^2, b in front of your x, and c will be the number without an x. Plug those into the equation and you'll get two answers. That will be it

Help me please I need the answer ASAP

ozzi

10.95x + 2.50, but for eight books so 10.95 x 8 + 2.50 = 90.10

12.50x + 4.50, but for six books so 12.50 x 6 + 4.50 = 79.50

To do this, we can set them both equal to each other and if x is a whole number of books, then they do pay the same amount. If x is a decimal, then they don't pay the same amount.

10.95x + 2.50 = 12.50x + 4.50

2.50 - 4.50 = 12.50x - 10.95x

-2 = 1.55x

This can never be a whole number, so therefore members and non-members can never pay the same amount for an order of x books.
