Answer 2

To solve the quadratic equation 4x^2 - 8x - 5 = 0, we can use the quadratic formula:

The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b^2 - 4ac)) / 2a

In our equation, a = 4, b = -8, and c = -5. Substituting these values into the formula, we get:

x = (8 ± √((-8)^2 - 4 * 4 * -5)) / 2 * 4 x = (8 ± √(64 + 80)) / 8 x = (8 ± √144) / 8 x = (8 ± 12) / 8

Now, we'll find two possible solutions:

1. x = (8 + 12) / 8 x = 20 / 8 x = 2.5

2. x = (8 - 12) / 8 x = -4 / 8 x = -0.5

Therefore, the solutions to the equation 4x^2 - 8x - 5 = 0 are x = 2.5 and x = -0.5.
