How would I slove the question in the attachment?
Ik that for the completing the square part it has to look like (x-5)^2 -3 but idrk what to do with that cause expanding it we get x^2 - 10x + 22

You must use the perfect square form
Complete the square then assume there is a constant
flint mesa
a quadratic y = ax^2 + bx + c can be written as
y = a(x-b)^2 + c
you know the minimum is 5,-3 so you can put that into ur completed square form
y = a(x-5)^2 - 3
now sub in (4,0)
0 = a - 3 --> a = 3

a quadratic y = ax^2 + bx + c can be written as
y = a(x-b)^2 + c
you know the m...
so whats b and c
oh nvm
its -30 for b
72 for c
