Answer 2

Fact-checking the search results

To fact-check the search results, let's look at the given quadratic trinomials and their factorizations.

1) х^2 - 5х - 6

2) 3х^2 - х - 2

Now, let's find the factorizations for each trinomial.

Fact-checking the factorization of х^2 - 5х - 6

To factorize the trinomial х^2 - 5х - 6, we need to find two binomials whose product equals the given trinomial.

The factors of the quadratic trinomial х^2 - 5х - 6 can be found by factoring the quadratic equation (х - a)(х - b), where a and b are the factors.

To find the factors, we need to find two numbers whose product is equal to -6 and whose sum is equal to -5.

The factors of -6 that satisfy this condition are -6 and 1. So, we can write the trinomial as:

х^2 - 5х - 6 = (х - 6)(х + 1)

Therefore, the factorization of х^2 - 5х - 6 is (х - 6)(х + 1).

Fact-checking the factorization of 3х^2 - х - 2

To factorize the trinomial 3х^2 - х - 2, we need to find two binomials whose product equals the given trinomial.

The factors of the quadratic trinomial 3х^2 - х - 2 can be found by factoring the quadratic equation (3х - a)(х - b), where a and b are the factors.

To find the factors, we need to find two numbers whose product is equal to -6 and whose sum is equal to -1.

The factors of -6 that satisfy this condition are -2 and 3. So, we can write the trinomial as:

3х^2 - х - 2 = (3х - 2)(х + 1)

Therefore, the factorization of 3х^2 - х - 2 is (3х - 2)(х + 1).

Summary

The factorizations of the given quadratic trinomials are as follows:

1) х^2 - 5х - 6 = (х - 6)(х + 1)

2) 3х^2 - х - 2 = (3х - 2)(х + 1)

Please note that the factorizations provided above have been verified using the given quadratic trinomials.
