Step-by-step explanation:
(distribute)
-3x -9 -3x + 3 + 8x = 4
(simplify)
2x -6 = 4
x=5

Vertex form is:
y = a(x - 1)^2 - 16 where a is a cosntant
at y intercept we have
-15 = a^2 - 16
a^2 = 1
so equation of the parabola is y = (x-1)^2 - 16
the equation of symmetry is x = 1 and both roots are same distance either side of the point (1,0) so the other x-intercept is 1 - 4 = (-3,0)
Assuming the missing signs are pluses, that would work out to a^3 + 12a^2 + 14a + 5
