Answer:
Step-by-step explanation:
There is a y² term, so the parabola is horizontal.
Vertex-form equation for a horizontal parabola:
x = a(y-k)² + h, where (h,k) is the vertex
If a>0, then
the parabola opens to the right
focal length p = 1/(4a)
focus (h+p,k)
directrix: x=h-p
endpoints of latus rectum: (h+p,k±2p)
Put equation into vertex form.
x = (1/12)y²
vertex (0,0)
focal length p = 1/(4·1/12) = 3
focus (0+p,0) = (3,0)
directrix: x = 0-p = -3
endpoints of latus rectum: (3,±6)
What you do is just find the missing value of the x.
x² + 10x = 26
x² + 10x + 25 = 26 + 25
x² + 5x + 5x + 25 = 51
x(x) + x(5) + 5(x) + 5(5) = 51
x(x + 5) + 5(x + 5) = 51
(x + 5)(x + 5) = 51
(x + 5)² = 51
x + 5 = ±√(51)
- 5 - 5
x = -5 ± √(51)
x = -5 + √(51) or x = -5 - √(51)
