Question

How would you get this into Vertex Form: y+60x+294=-3x^2?

Answer 1

y = -3x^2 - 60x - 294.

Can u solve the RIGHT side now?

Answer 2

Yes, but I got 3x^2 +60x+294=-y and I don't know what to do after this.

Answer 3

No, you can't take y as negative.

Answer 5

This is what I did: \[y+60x+294=-3x^2\] and I took away y from each side and got:\[60x+294=-3x^2-y\]

Answer 6

y = ax^2 + bx + c

U have to bring to this form^

Answer 7

then I added 3x^2 to both sides and got: 3x^2 +60x+294= -y.

Answer 8

now, multiply the whole equation by -1, so that u can get y as positive.

Answer 9

So it would be this: -3x^2 -60x-294=y?

Answer 10

YES! correct.

Answer 11

Now solve the equation

Answer 12

Okay. Thanks for your help.

Answer 13

No problem
