Question

Convert y = 8x^2-80x-32 to vertex form by completing the square. ​

Answer 1

y = 8 (x - 5)^2 - 232

Explanation:

Dividing the whole equation by 8, we get:

y = 8 (x^2 - 10x - 4)

y = 8 (x - 5)^2 - 232

Hope this helps!

Answer 2

y = 8(x-5)^2 -232

Explanation:

Factor out the 8 to get

y = 8(x^2-10x-4)

y = 8(x-5)^2 -232
