Factoring using the criss cross method

Front

What is the criss cross method in factoring?

Back

The criss cross method is a technique used to factor quadratic expressions by rearranging the coefficients and constants in a specific way to find two binomials that multiply to the original expression.

What is the first step in factoring using the criss cross method?

Back

The first step is to identify the coefficients of the quadratic expression and set up a grid to rearrange them.

What does it mean for an expression to be 'not factorable'?

Back

An expression is 'not factorable' if it cannot be expressed as a product of two or more simpler expressions, typically when it is prime.
