Answer:
The solutions of the equation are
(8+2 √(65) )/(7) and
(8-2 √(65) )/(7)

Step-by-step explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
7x² - 16x - 28 = 0

By comparing:
a = 7
b = -16
c = -28

Now, to get the roots, we will use the quadratic formula shown in the attached image.

Substitute with the values of a, b and c and calculate the corresponding roots.

You will get the roots:

(8+2 √(65) )/(7) and
(8-2 √(65) )/(7)

Hope this helps :)
