What are the two solutions of 2x2 = –x2 – 5x – 1?

1)the y-coordinate of the intersection points of the graphs of y = 2x2 and y = –x2 – 5x – 1
2)the x-coordinates of the x-intercepts of the graphs of y = 2x2 and y = –x2 – 5x – 1
3)the x-coordinates of the intersection points of the graphs of y = 2x2 and y = –x2 – 5x – 1
4)the y-coordinates of the y-intercepts of the graphs of y = 2x2 and y = –x2 – 5x – 1

The right answer is 3)

We have the following equation:

This equation can be solved using the Quadratic Formula:

On the other hand, as the statement establishes, we have two functions:

So, the x-coordinates of the intersection points (as indicated in the Figure bellow) of these two graphs are the same points obtained by using the Quadratic Formula.

x/7.50 = 15

x= 7.50 / 15 divide
