Step-by-step explanation:
you have to add and substract is easy
You could add the whole number parts first then add the fractions. Finally add the 2 results.
My recommendation would be to factor..
x² + 4x + 3 = 0 factor the left side into two binomials
(x + 3)(x + 1) = 0 set each of these binomials equal to zero and solve
x + 3 = 0 Implies x = -3
x + 1 = 0 implies x = -1
