Which equation is y = 2x2 – 8x + 9 rewritten in vertex form?

y = 2(x - 2)² + 1

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = 2x² - 8x + 9

Using the method of completing the square

Factor out 2 from the first 2 terms

y = 2(x² - 4x) + 9

add/subtract ( half the coefficient of the x- term )² to x² - 4x

y = 2(x² + 2(- 2)x + 4 - 4) + 9

   = 2(x - 2)² - 8 + 9

   = 2(x - 2)² + 1 ← in vertex form

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.
