Answer:
5/28
Step-by-step explanation:
The equation of a parabola has 4 general equations:
(x - h)² = 4a(y - k)
(x - h)² = -4a(y - k)
(y - k)² = 4a(x - h)
(y - k)² = 4a(x - h)
You will notice that the equation contains an x². So, our choices will be narrowed down to:
(x - h)² = 4a(y - k)
(x - h)² = -4a(y - k)
where, the vertex has the coordinates (h.k)
y = 6x² - 24x + 30
Divide both sides by 6,
y/6 = x² - 4x + 5
y/6 - 5 = x² - 4x
Completing the squares, add (-4/2)² = 4 to both sides,
y/6 - 5 + 4 = x² - 4x + 4
y/6 - 1 = (x - 2)²
1/6(y - 6) = (x - 2)²
Thus, h=2 and k=6. The vertex is at point (2,6).

Answer:
1
x
−
5
Explanation:
The key realization is that our denominator fits the difference of squares pattern
a
2
−
b
2
, which factors as
(
a
+
b
)
(
a
−
b
)
.
We can rewrite
x
2
−
25
as
(
x
+
5
)
(
x
−
5
)
, which allows us to rewrite our original expression as
x
+
5
(
x
+

)
(
x

)
The
