We know f(x)=5x+1. Plug in f(x) in the g(x) function.
We get

Distribute the 2 to 5x and 1.

Simplify to get

Now, we plug in -1 for x.

Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0
