Answer: the roots of the equation are : -3, -1
Step-by-step explanation:
[tex]x^{2}[/tex] + 4x + 3 = 0
by factorizing
(x+1)(x+3) = 0
x+1 = 0 or x + 3 =0
x = -1 or x = -3
Answer:
x = - 3 and x = - 1
Step-by-step explanation:
Given
x² + 4x + 3 = 0 ← in standard form
(x + 3)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 1 = 0 ⇒ x = - 1
