Answer 2

Answer:

option c

Step-by-step explanation:

x square+4x+3=0

1. x square +x+3x+3=0
2. common form above equation
3. xis common from x square +x then x (x+1) _eq_1
4. same step for 3x+3 also then 3 (x+1) _ eq_2
5. from equation 1 and 2
6. x (x+1)+3 (x+1)=0
7. now (x+1)(x+3)=0
8. both are equal to zero
9. so, (x+1)=0
10. x=-1
11. now (x+3)=0
12. x= -3
13. answer is (-1,-3)
