College algebra homework having issues calculating this by hand and on ti-84 receiving errors like "8e12" when trying to calculate the actual quadratic equation it calls for in question

checking the vertex of this upside-down parabola, it has a vertex at (1000, 2000000), so that's the U-turn, when as the price "p" increases the revenue goes down.

now, if we solve the quadratic using the value of 500000

and we run the quadratic formula on it, we get the values of x = 133.97 and x = 1866.03, one value is obviously when going upwards, the first one, and the other is when going downwards.

so we know that the R(p) is 500,000 at x = 133.97, and it keeps on going up, up to the vertex above at x = 1000, so we can say from x = [134, 1000] R(p) > 500000.

the equivalent expression are always the hardest ones but you look at the gcf also
