Answer:
Explanation:
you are being asked to "Solve a quadratic"
There are various METHODS to do this.
You will learn a few of them
-graphing
-substation
-complete the square
-quadratic formula
in this case the question wants you to solve it using the
Quadratic formula...
Ax^2 + Bx + C = 0 is the quadratic.
your A=-1 B=14, and C=61
you just have to plug in those numbers into:
±

-14 ±

you should end up with 7+
& 7-

which is -3.49 or 17.49
-3.49 does not make any sense, the 17.49 distance only makes sense for this problem
