Question

The vertex form of the equation of a parabola is y = (x - 5)2 + 16.
What is the standard form of the equation?
A. y = x2 - 10x + 41
B. y = x2 + 10x + 16
C. y = x2 + x + 8
D. y = 3x2 - 10x + 41

Answer 1

\[ y = (x - 5)^2 + 16\\
y=(x-5)(x-5)+16\] etc

Answer 2

multiply out, combine like terms

Answer 3

A. y = x2 - 10x + 41
B. y = x2 + 10x + 16
C. y = x2 + x + 8
D. y = 3x2 - 10x + 41
