Answer:
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)
Step-by-step explanation:
we have

we know that
The roots of the quadratic function are the values of x when the value of the function is equal to zero
so
For f(b)=0

Solve for b
Adds 75 both sides

take square root both sides

Simplify

therefore
(b = 5 StartRoot 3 EndRoot)
and
(b = Negative 5 StartRoot 3 EndRoot)
