Factoring Trinomials Using Slide & Divide

Front

What is a trinomial?

Back

A trinomial is a polynomial with three terms, typically in the form ax^2 + bx + c.

Front

What does it mean to factor a trinomial?

Back

Factoring a trinomial involves rewriting it as a product of two binomials.

Front

What is the 'Slide & Divide' method?

Back

The 'Slide & Divide' method is a technique for factoring trinomials where you first multiply the leading coefficient by the constant term, then factor the resulting quadratic.

Front

How do you identify the leading coefficient in a trinomial?

Back

The leading coefficient is the coefficient of the term with the highest degree (the first term when written in standard form).

Front

What is the first step in the 'Slide & Divide' method?

Back

Multiply the leading coefficient (a) by the constant term (c) in the trinomial ax^2 + bx + c.

What is the purpose of the 'Slide' in the 'Slide & Divide' method?

Back

The 'Slide' refers to moving the leading coefficient down to the second binomial after factoring the quadratic.

Front

What is the purpose of the 'Divide' in the 'Slide & Divide' method?

Back

The 'Divide' refers to dividing the factors by the leading coefficient to simplify the binomials.
