Question

A parabola has equation y - 7 = 3(x + 2)^2.
Rewrite the equation in the form
Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0.

Answer 1

Expand the binomial (x+2)^2 , put all terms on the left and in the proper order. Use 0 for a coefficient if there is no such term.

Answer 2

what about the -7?

Answer 3

check me, please:
3x^2+12x+-1y+19=0

Answer 4

Hang on. I will.

Answer 5

y-7=3(x+2)^2=
y-7=3(x^2+4x+4)
y-7=3x^2+12x+12
3x^2+12x-y+19=0

Answer 6

Yep. I agree.
