Answer 2

Solving the Equation x² + zx + 8 = 0

To solve the equation x² + zx + 8 = 0, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, the equation is x² + zx + 8 = 0. Comparing it to the general form ax² + bx + c = 0, we can see that a = 1, b = z, and c = 8. Plugging these values into the quadratic formula, we get:

x = (-z ± √(z² - 4(1)(8))) / (2(1))

Simplifying further, we have:

x = (-z ± √(z² - 32)) / 2

This is the general solution for the equation x² + zx + 8 = 0. The specific values of x will depend on the value of z. If you provide a specific value for z, I can calculate the solutions for you.
