The zeros is another name for solutions.
x^2 - 5x - 1 = 0
You must use the quadratic formula to find x.
In the formula, a = 1, b = -5 and c = -1.
Plug into formula and solve for x.
The values of x are the zeros of the function.

Answer:
Sheet metal remaining = 4.1x
cost per square foot of sheet metal = $30
Step-by-step explanation:
Total sheet metal bought = 7.6 ft2
Total sheet metal used = 3.5 ft2
Given equation:
7.6x − 3.5x = 123
Where,
x = cost per square foot
7.6x − 3.5x
Sheet metal remaining = 4.1x
7.6x − 3.5x = 123
4.1x = 123
x = 123 / 4.1
x = $30
Cost per square foot = $30
Answer: $103.88
