What does GCF stand for in factoring trinomials?

Back

GCF stands for Greatest Common Factor, which is the largest factor that divides all terms in a polynomial.

How do you find the GCF of the terms in a trinomial?

Back

To find the GCF, identify the highest common factor of the coefficients and the common variable factors in each term.

Front

What is the first step in factoring a trinomial?

Back

The first step is to look for the GCF of all the terms and factor it out.

What is a trinomial?

Back

A trinomial is a polynomial with three terms, typically in the form ax² + bx + c.

Front

How do you factor a trinomial in the form ax² + bx + c?

Back

To factor a trinomial, find two numbers that multiply to ac (the product of a and c) and add to b.

Front

What is the factored form of a trinomial?

Back

The factored form of a trinomial is expressed as (px + q)(rx + s), where p, q, r, and s are constants.

Front

What is the significance of the leading coefficient in factoring trinomials?

Back

The leading coefficient (a) affects the method used to factor the trinomial, especially when a is not equal to 1.

Front

What is the difference between factoring by grouping and factoring trinomials?

Back

Factoring by grouping involves rearranging terms and grouping them to find common factors, while factoring trinomials focuses on finding two binomials that multiply to the trinomial.

What is the role of the discriminant in factoring quadratics?

Back

The discriminant (b² - 4ac) determines the nature of the roots of the quadratic equation; if it's positive, there are two distinct real roots.

How can you check if your factored form is correct?

Back

You can check by multiplying the factors back together to see if you obtain the original trinomial.
