Answer:
y = 4x² - 16x + 16
Step-by-step explanation:
Standard form is y = ax² + bx + c
To convert from vertex form to standard form multiply out the equation
1. Solve (x-2)² using F.O.I.L.
(x - 2) · (x - 2) = x² - 4x + 4
y = 4(x² - 4x + 4)
2. Distribute the 4
y = 4x² - 16x + 16
Answer:
I need this answer so badly
Answer:
Numbers are 14 and 8
Step-by-step explanation:
Let the 2 numbers be x and y.
Write 2 equations:
x + y = 22
x - y = 6
Solve by substitution:
x - y = 6
x = y + 6
Plug into the other equation:
(y + 6) + y = 22
2y + 6 = 22
2y = 16
y = 8
Plug into either equation:
x + 8 = 22
x = 14
Numbers are 14 and 8
I think 5x sorry if this doesn't help<span />
