The given one is a second degree expression for x and first degree for y; so this represents a parabola with its axis parallel to y-axis, that is called vertical axis symmetry parabola;
The standard form for this is: (x - h)^2 = 4a(y - k)
Hence the standard form for this is: {x - (-3)}^2 = (1/4)(y - 3)
Another standard form is axis, parallel to x-axis, which is called a horizontal axis of symmetry;

y -3 = 4(x+3)^2
y = 3 + 4(x+3)^2
y = 4x^2 + 24x + 39
First, you have to identify "standard" form. The general form of a quadratic, or 2nd order, equation is:
ax² + bxy + cy² + dx + ey + f = 0
If that's the form you're looking for, expand the equation to separate the terms so that they match the desired form of the equation:
y-3 = 4(x+3)²
y-3 = 4(x²+6x + 9)
y-3 = 4x²+24x+36
and the general form of the equation is:
4x² + 24x - y + 39 = 0
with:
a = 4
b = 0
c = 0
d = 24
e = -1
f = 39
The equation is also the equation of a parabola which can be written in standard "vertex" form as:
y = 4(x+3)² + 3
So, what is the "standard" form you're searching for?
1/4(y-3) = (x+3)^2
y = 4 ( x + 3 ) ² + 3 is the answer.
If desired :-
y = 4 ( x ² + 6 x + 9 ) + 3
y = 4 x ² + 24 x + 39

here the standard form is: (y - k)^2 = 4a(x - h)
y = 4(x+3)^2 + 3
that's all you have to do.
you can do more by simplifying, but this is an acceptable answer.

Well, first off, isn't the standard form ax+by=c?
If it is, then I believe the answer is:
4x^2 + (-y) = -27
If it isn't... then don't listen to me. =)
y-3=4(x²+6x+9)
y-3=4x²+24x+36
y=4x²+24x+39
look in the back of the book or on google
