Answer 2

To solve the quadratic equation 5x^2 - 7x - 6 = 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 = 5, b = -7, and c = -6. Let's substitute these values into the quadratic formula and find the solutions:

x = (7 ± √((-7)^2 - 4 * 5 * -6)) / 2 * 5

x = (7 ± √(49 + 120)) / 10

x = (7 ± √169) / 10

Now, calculate the square root of 169:

√169 = 13

So, the solutions for x are:

x = (7 + 13) / 10 or x = (7 - 13) / 10

x = 20 / 10 or x = -6 / 10

x = 2 or x = -0.6

Therefore, the solutions to the equation 5x^2 - 7x - 6 = 0 are x = 2 and x = -0.6.
