Bror cancelled terms which should NEVER be done.
x² + 3x + 2 / (x + 2) =
(x+1) * (x+2) / (x+2)

Cancelling the (x+2) factor we get
x + 1

The solution to the given quadratic equation is;

x = -2 and x = 1/5

<h3>Roots of quadratic Equation </h3>

We are given the quadratic function;

(x + 2)(5x - 1) = 0

In quadratic functions, when it is expressed as;

(x + a)(x - b) = 0, what this means is that the factors of the quadratic equation or polynomial are; (x + a) and (x - b)

What that means is that the roots will be gotten from;

(x + a) = 0 and (x - b) = 0

Thus, applying the concept above on roots of a polynomial to our question, we have;

(x + 2) = 0 and 5x - 1 = 0

Solving them gives us;

x = -2 and x = 1/5
