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
The answer to your question is 3:23
Type it into the app or online on ‘Desmos’ it a really good graphing calculator. I hope this helps
