Question

Find the zeros, axis of symmetry and vertex for the following functions, using the specified methods to find the zeros.

a)
`x^2-6x+9=y` factoring
b)
`x^2+4x=12x+y` completing the square
c)
`(x-2)^2-3=y` quadratic formula
Please include explanations

Answer 1

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

b) x²-8x-y

c) x¹= 4.5, x²= -0.4

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
