This is a quadratic equation of the form ax^2 + bx + c = 0. We can solve it using the quadratic formula, which is x = [-b ± sqrt(b^2 - 4ac)] / (2a).

Here, a = 7, b = 22, and c = 3.

Step 1: Calculate the discriminant, which is b^2 - 4ac.
Discriminant = (22)^2 - 4*7*3 = 484 - 84 = 400.

Step 2: Substitute a, b, and the discriminant into the quadratic formula to find the solutions.

x = [-22 ± sqrt(400)] / (2*7)
x = [-22 ± 20] / 14

So, the solutions are x = -42/14 = -3 and x = -2/14 = -1/7.
