Answer:
x = -2, -3
Step-by-step explanation:
First, factor out the Greatest Common Factor (GCF).
3([tex]x^{2}[/tex] + 5x + 6) = 0
Then, find 2 numbers two numbers which add to 5 and multiply to 6:
2 + 3 = 5
2 * 3 = 6
Set both numbers as factors:
3(x + 2)(x + 3) = 0
Set both parentheses to 0:
(x + 2) = 0
x = -2
(x + 3) = 0
x = -3
x = -2, -3
