Answer:the pages will come on the first is 210
Explanation:
Since we have given that two pages that face each other in a book
i.e. they must be consecutive to each other
so, let the first page number be x
and the second page number be x+1
According to question,

2x=421 -1
2x=420

So, the pages will come on the first is 210
if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation

now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
