Question

can someone check this for me>

Answer 1

everything looks really good...except #74 error should be
y = (x-1)^2 -10

Answer 2

Okay and how would I do this:

y= 3x^2 - 12x + 1

Answer 3

^do what? complete the square...?

first factor out the 3 \[\large y= 3x^2 - 12x + 1\] \[\large y= 3(x^2 - 4x) + 1\]

Answer 4

then divide by 3?

Answer 5

No, complete the square from there

Answer 6

how would I do that @agent0smith

Answer 7

The same way you did all those other questions (it seems like you know how to complete the square already). You just have to not forget about the 3.
