express each equation in the specified form.
a)y=(x-3)^2-25 in standard form
b)y=2(x-7)(x 3) in standard form
c)y=-2x^2 28-26 in factored form
d)y=-9x^2 72x 81 in vertex form

a) Expand the exponentiation:
y = x^2 - 6x + 9 - 25
Combine like terms:
y = x^2 - 6x - 16
The others are all missing signs which are necessary to the answers.
