Question

The vertex form of the equation of a parabola is y= (x + 5)2 + 49.

What is the standard form of the equation?

Answer 1

y = x² + 10x + 74

Step-by-step explanation: i just took the test

Answer 2

y = x² + 10x + 74

Explanation:

Given

y = (x + 5)² + 49 ← expand the factor using FOIL

= x² + 10x + 25 + 49

= x² + 10x + 74 ← in standard form
