Write y = 2x2 + 8x + 3 in vertex form.

y = 2 * (x +2)² - 5

Step-by-step explanation:

y = 2 * x² + 8x +3          v(h,k)

y = 2 (x-h)² + k = 2x² - 4xh + 2h² + k

8x = -4xh         h = -2

2h² + k = 3    

8 + k = 3      ∴ k = -5

Vertex form : y = 2 * (x +2)² - 5

step-by-step explanation:

if x = 2 you have to find x to finish the problem

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
