subtract 12x squared and factor and the equation will be equal to zero then u can factor
The vertex is always halfway between the focus and the directrix, and the parabola always curves away from the directrix, so I'll do a quick graph showing the focus, the directrix, and a rough idea of where the parabola.
<span>So the vertex, exactly between the focus and directrix, must be at <span>(h, k) = (1,
–2)</span><span>. The absolute value of </span>p<span> is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on </span>p<span>tells me which way the parabola faces.) Since the focus and directrix are two units apart, then this distance has to be one unit, so </span><span>| p | = 1</span>.<span>Since the focus is to the left of the vertex and directrix, then the parabola faces left (as I'd shown in my picture) and I get a negative value for </span>p<span>: </span><span>p = –1</span><span>. Since this is a "sideway" parabola, then the </span>y<span> part gets squared, rather than the </span>x<span> part. So the conics form of the equation must be:</span>(y<span> – (–2))2 = 4(–1)(x – 1)</span><span>, or </span><span>(y<span> + 2)</span>2<span> = –4(</span>x<span> – 1)</span></span>

The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2
When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4
Answer: The coefficient of the squared expression in the parabola's equation is 4
Answer: Option B. 4
