The solution to the equation are 5 or -1 after applying the quadratic formula.
<h3>What is a quadratic equation?</h3>
Any equation of the form
where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
It is given that:
x² - 4x² - 5 = 0
The above equation is a quadratic equation:
Using the quadratic formula:

Plug the values in the formula:

After solving:
x = 5 or -1
Thus, the solution to the equation is 5 or -1 after applying the quadratic formula.
