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 is ax^2 + bx + c = 0, where a, b, and c are constants.

Front

What is the first step in factoring a trinomial?

Back

Identify the coefficients a, b, and c in the trinomial ax^2 + bx + c.

Front

How do you find two numbers that multiply to ac and add to b?

Back

Look for two numbers that, when multiplied, equal the product of a and c, and when added, equal b.

What is the difference of squares?

Back

The difference of squares is a special case of factoring, expressed as a^2 - b^2 = (a - b)(a + b).
