Factoring Trinomials (a=1)

Front

What is a trinomial?

Back

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

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 standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants.

How do you determine if a trinomial is prime?

Back

A trinomial is prime if it cannot be factored into the product of two binomials with real coefficients.

What is the relationship between the coefficients and roots of a trinomial?

Back

The sum of the roots is equal to -b/a and the product of the roots is equal to c/a in the trinomial ax^2 + bx + c.
