Answer:
Step-by-step explanation:
Given is an equation connecting 3 variables D, e and f. Each depends on the other
The given equation is a solution in variable D as
To solve for e, we have to finally have e on one side and all other terms on the other side
Hence first interchange left and right side as
Divide both sides by 3 f square
This is the solution for e

<u>Given functions</u>:
Solve for p(x) = r(x):
As the found quadratic equation cannot be factored, use the Quadratic Formula to solve for x:
<u>Quadratic Formula</u>
Therefore:
Substitute the values of a, b and c into the <u>quadratic formula</u> and solve for x:
Therefore, the solutions are:

Answer:
141, meaning that there will be two real solutions
Step-by-step explanation:
The discriminant of a quadratic is , which in this case is:
Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.
