Step-by-step 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:

± $\sqrt{\frac{B^{2}-4AC}{2A}}$

-14 ± $\sqrt{\frac{14^{2}-4(-1)(61)}{2(-1)}}$

you should end up with 7+ $\sqrt{110}$ & 7- $\sqrt{110}$

which is -3.49 or 17.49

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