Answer:
240
Step-by-step explanation:

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

Combine like terms.

Solve the equation by factoring.

Hence the values of x that make f(x) = g(x) are -3 and 1.

Let me know if you have any doubts!
The only thing I can think of to rewrite this is either 8+72t or changing the variable to a different letter. The expression is already in its simplest form.
That is a ratio. 7 x 3 = 21 and 13 x 3 = 39.
