Please be a little more specific on what you want to ask.
I can be of some help.
You use the formula given and it usually involves dividing
Answer:48
Step-by-step explanation:
Answer:
y = 2x^2 − 4x + 5
y = 2(x^2 − 2x) + 5
y = 2(x^2 − 2x + 1 - 1) + 5
y = 2(x^2 − 2x + 1) + 5 - 2
y = 2(x - 1)^2 + 3
x = 1 is the axis of symmetry.
Do you agree?
7 i just squared root 49 because 49 is a perfect square
