Find the zeros, axis of symmetry and vertex for the following functions, using the specified methods to find the zeros.
a) factoring
b) completing the square
c) quadratic formula
include explanations

a) (x-3)(x-3)

b) x²-8x-y

c) x¹= 4.5, x²= -0.4

Step-by-step explanation:

a) x²-6x+9 = x-3 X x-3

b) x²+4x-12x-y = x²-8x-y

c) formula for quadratic formula is -b±√b²-4ac/2a

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
