How do u solve x^2+4x+3=0

Question

I could really use help on this algebra question 

Answer 1

You can factor the expression or use the quadratic formula.

 

Factoring:

 

(x + 1)(x + 3) = 0

 

Solve for x and get x = -1 or -3.

 

Quadratic formula:

 

x = -{4 ±√[4² - 4(1)(3)]}/[2(1)] = -1 or -3
