Answer:
Step-by-step explanation:
A quadratic equation can be factorised if and only if there are rational roots.
For any quadratic equation the discriminant decides about the nature of roots.
Thus only if the discriminant is a perfect square we can have rational roots and in this case only factorization is possible.
In the given equation

Since 1 is a perfect square we can factor and solve

I’m pretty sure the correct answer is B
Answer:
Step-by-step explanation:
It is the 2nd one and 4th one. The x intercepts are -1 and -3, so the factors are x + 3 and x + 1. The 4th choice is the actual equation and the 2nd is the factors
1) 1 1/6
2) 1 1/6
4) 5 1/ 18
hope you got your answer i didn't know what number 3 was so i did the rest
