Factoring Trinomials with a=1

What is the primary goal when factoring trinomials in the form x^2 + bx + c?

• To find two numbers that multiply to c and add to b

• To find two numbers that multiply to b and add to c

• To subtract the constant term from the middle term

• To divide the trinomial into multiple binomials

In the case of a trinomial with a leading coefficient of 1, how do you determine the binomial factors?

• By multiplying the constant term by the middle term coefficient

• By finding two factors of the constant term that add to the middle term coefficient

• By finding any two factors of the constant term

• By dividing the constant term by the middle term coefficient

What is the greatest common factor (GCF) used for in the context of factoring trinomials?

• To determine the coefficients of the binomials

• To adjust the signs of the factors

• To find the factors of the constant term

When factoring trinomials, why is it important to consider the greatest common factor first?

• It simplifies the trinomial making the factoring process easier

• It changes the signs of the factors

• It increases the value of the constant term

• It has no impact on the factoring process
