The solutions for the quadratic equation are given as follows:

x = -1, x = 7/5

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

The solutions are:

$x_1 = \frac{-b + \sqrt{\Delta}}{2a}$

$x_2 = \frac{-b - \sqrt{\Delta}}{2a}$

In which:

$\Delta = b^2 - 4ac$

For this problem, the equation is:

5x² - 2x - 7 = 0.

Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:

$\Delta = (-2)^2 - 4(5)(7) = 144$

$x_1 = \frac{2 + \sqrt{144}}{10} = \frac{7}{5}$

$x_2 = \frac{2 - \sqrt{144}}{10} = -1$

The solutions are:

x = -1, x = 7/5
